VidaBay launches Duo, a dual-sided E Ink bag charm

VidaBay has launched Duo, its first double-sided electronic paper bag charm, in Hong Kong with NFC-based image transfer and no battery or charging required. The new product is aimed at holiday gifting and is now on sale on VidaBay’s global and Japan online stores.

Why it matters: - Duo extends VidaBay’s battery-free E Ink lineup beyond the Snap refrigerator magnet and into wearable accessories. - The product combines customizable display surfaces with NFC features, which gives the charm both a personal-photo use case and a digital-sharing function. - VidaBay is positioning Duo as a holiday gift, with pricing set to stay below the brand’s standard launch price during Black Friday.

What happened: - VidaBay officially launched Duo, a double-sided E Ink bag charm, on November 12, 2026, in Hong Kong. - Duo lets users display different images on the front and back. - The product uses VidaBay’s NFC-based, battery-free image transfer technology. - VidaBay says Duo can be updated without charging. - The company also began formal sales in Japan through its Japanese online store.

The details: - Duo uses a 2.67-inch high-pixel-density E Ink display. - The charm has a rounded design and uses transparent blue and purple acrylic. - Users can set separate images for each side through the VidaBay app. - The built-in NFC tag can open linked music, video, websites, digital business cards and apps when a smartphone is tapped against the charm. - Duo is sold on VidaBay’s global site at the company’s shop for $65.99 for a single unit. - The Black Friday price on the global site is $54.99. - VidaBay’s Japan store is offering 20% off all products during Black Friday. - VidaBay says its E Ink approach keeps the product battery-free and reduces the need for routine maintenance.

Between the lines: - Duo builds on the attention VidaBay received for Snap, which was highlighted by E Ink Corporation and featured in gift guides and media coverage including The Verge, TechRadar and Numerik Media. - The product pitch blends sentimental gifting with practical NFC utility, suggesting VidaBay is aiming at buyers who want both personalization and digital connectivity in one accessory. - The company is leaning on a familiar display panel and battery-free design to keep the new product relatively affordable.

What’s next: - VidaBay is now selling Duo through its main online storefront and its Japan site. - Black Friday promotions are the immediate commercial focus, including a launch discount on Duo and a sitewide discount in Japan. - VidaBay is likely to continue building its battery-free product line around the same E Ink platform used in Snap.

The bottom line: - Duo turns VidaBay’s battery-free E Ink concept into a more portable, gift-friendly product, while adding NFC features that make the charm more than a static display.
