This Card Wallet Replaces Sticky Notes With a Reusable Board

The sticky note has outlasted every productivity trend that was supposed to replace it, and there’s a reason for that. Writing something down by hand, right when it occurs to you, is still the fastest way to keep an idea from slipping away. Digital apps, meanwhile, have the opposite problem: the moment you unlock your phone to jot something down, you’re one notification away from forgetting why you opened it.

New Things Lab, a design studio from the Netherlands, built a direct answer to that problem. The MEMO Whiteboard Wallet is a precision-machined aluminum card holder with a dry-erase surface built directly into its face, giving you a pocket-sized board that’s always ready when a thought strikes. The concept earned quite a following from people who immediately understood what it was for.

Designer: New Things Lab

The whiteboard spans 6 inches diagonally, just over A7 in size, and it’s coated with a smooth, heat-cured paint that cleans up without ghosting. It’s large enough to be genuinely useful but slim enough not to add awkward bulk. On a given day, you might use it to jot down a measurement, scribble a password for a guest, or keep a short list of things you’d otherwise forget by lunch.

Writing on the surface is handled by an included 0.8mm fine-point pen that stores in a dedicated slot built right into the wallet’s frame, so it’s always within reach when you need it. Flip the pen around, and there’s an eraser on the other end, making the MEMO genuinely self-contained. You’re not hunting for something to wipe the board with, and there’s no spare piece you’d misplace in a bag.

On the other side of the MEMO is the actual card-carrying section, with room for up to six standard cards and a magnetic closure that keeps everything neatly shut. The body is milled from 6063 aluminum, giving it a solid, premium feel without adding unnecessary weight or thickness. That same metal shell also blocks RFID signals, protecting your card data from electronic skimming without needing any additional sleeve or pouch.

The MEMO comes in Charcoal Black, Slate Gray, and Gilded Rose as the standard colorways, with Revision Red and Airmail Blue available as limited editions. All five options lean toward the restrained end of the color spectrum, which suits the product well. There’s also an environmental case to be made here. Every note wiped from the MEMO’s surface is a sticky note that didn’t find its way into the trash, and those savings do compound over time.

MWC 2026’s most bizarre phone can start fires (on purpose)

This isn’t a Galaxy Note 7 debacle. Oukitel's WP63 is a ruggedized smartphone that’s meant to set things alight. It has a built-in electric igniter, aimed at emergency response and camping, helping to start fires when you forgot matches, but you brought this beastly phone along for the adventure. It’s got several other notable features, like a 20,000mAH battery, a loudspeaker, and even its own built-in USB-C cable for charging other devices.

Still, the igniter was why I was here. The WP63 has an electric coil that heats up, similar to cigarette lighters in cars circa 1987. This is hidden away behind a protective cover at the top of the device, and once it pops out, you activate it using an app. An Oukitel spokesperson was able to light some rolled-up paper, and I was surprised how gentle and seemingly in control it was. (The paper looked like a cigarette, too.)

Unfortunately, another spokesperson told me that it can’t be used to light candles, although I can’t understand why. I don’t start campfires, but I do light candles.

The phone will be priced at $399. and completely ignoring the tendency for thinner and thinner phones, it’s 27mm thick. Another outdoor use? If a bear decided to attack you in the woods, you might be able to concuss it with the WP63.

Update, March 4 2026, 7:30AM ET: Oukitel says the phone will be priced at $399.

RayNeo Just Put Batman on $299 AR Glasses (And They’re Brilliant)

At some point between CES announcements and MWC reveals, someone at RayNeo had a genuinely inspired idea. They had built the world’s first AR glasses with HDR10 support, partnered with Bang & Olufsen on the audio, and engineered a display that could hold its own against high-end monitors. The product was technically impressive, competitively priced, and ready to ship. Then they added a Batman mask to it. Not a sticker, not a themed wallpaper, but an actual light-blocking cover that makes you look like you are about to patrol Gotham while watching movies on a 201-inch virtual screen.

This is the Air 4 Pro, unveiled at MWC 2026 in Barcelona, and it represents something rare in the wearables market: a product that takes itself seriously enough to deliver legitimate specs, but not so seriously that it forgets to be fun. The hardware alone would make this newsworthy. The fact that it comes with the option to cosplay as either Batman or the Joker while using it makes it irresistible.

Designer: RayNeo

Start with what matters most: the display. The Air 4 Pro is the world’s first AR glasses with HDR10 display support, which is a genuinely significant leap. Powered by RayNeo’s custom Vision 4000 chip, the display hits 1,200 nits of peak brightness, renders 10.7 billion colors with near-professional color accuracy (ΔE < 2), and runs at a smooth 120Hz refresh rate. We're talking about a 201-inch virtual screen that sits in front of your eyes, with a 200,000:1 contrast ratio. That is the kind of color performance you would expect from a high-end monitor, not from something you're wearing on your face.

The HDR10 support matters more than it might seem at first. It means that when you’re watching a movie or gaming with these on, the image is not being compressed into mediocrity. The Vision 4000 chip can also upgrade standard SDR content to HDR in real time, and there is an AI algorithm onboard that converts 2D content into 3D. These are not gimmick features. For anyone who has tried AR glasses before and felt vaguely disappointed by the visual output, this is the version that corrects the course.

Audio-wise, RayNeo partnered with Bang & Olufsen on a self-developed sound tube design with a dual opposing acoustic chamber system. The result is reportedly an 80% reduction in sound loss compared to previous models. That is a partnership that immediately signals intent. Bang & Olufsen does not lend their name to anything half-hearted, and the presence of that collaboration here suggests that RayNeo is going after people who care about the full sensory experience, not just the display numbers.

The glasses weigh 76 grams, which is no small achievement given everything packed inside. They include interchangeable nose pads, TÜV SÜD certification for low blue light and flicker-free performance, and a 3,840Hz PWM hybrid dimming system for eye protection. It is the kind of spec sheet that feels increasingly grown-up.

And then there is the Batman Edition. RayNeo unveiled two limited versions at MWC 2026: the Limited Justice Edition, which is the Batman variant, and the Limited Chaos Edition, styled after the Joker. Both come with a light-shield cover that doubles as a cosplay accessory, blocking ambient light to sharpen your viewing experience while also making you look like you are about to interrogate someone in Gotham City. The packaging is loaded with DC-themed details, and buyers get to literally pick a side.

Is this a marketing stunt? Partially, yes. But it is a clever one, because the light-shield cover is functional, not just decorative. It actually solves a real problem AR glasses have always had in bright environments. The fact that it also looks incredible is a bonus that makes this feel less like a product and more like a collectible.

My honest take is that the Batman collaboration is what will get people through the door, but the hardware is what will make them stay. At $299, with an early bird price of $249 through March 28, the Air 4 Pro is not cheap, but it is positioned well against the competition. It works with iPhones, Android flagships, PS5, Nintendo Switch 2, and most modern devices, which removes a lot of the friction that has held wearables back.

RayNeo has clearly done its homework. The Air 4 Pro is not trying to replace your phone or your TV. It is offering a better version of the portable screen experience, and the Batman costume is just the perfect way to announce it.
