Coolnut B21 Inkless Bluetooth Thermal Label Printer — 2 Inch (0.8''–2'') Sticker Maker for Small Business, Clothing, Mailing, Barcodes

The Coolnut B21 is a compact thermal label printer designed for 0.8''–2'' label widths, ideal for small businesses and home projects — clothing tags, crafts, retail items, jewelry, addresses, mailing, barcodes, transportation labels, name tags, date labels and party or holiday uses (Christmas, birthdays, Thanksgiving, Father’s Day, Mother’s Day). Its inkless thermal technology means you only change the label paper; there’s no need to buy ink, toner, or carbon tape. A single battery charge provides 4 hours of use, and the unit automatically powers off after 15 minutes of inactivity to save power, helping cut printing costs by up to 70%. The B21 connects to your phone via Bluetooth and uses a feature-rich app. The upgraded app includes image analysis for higher-resolution, sharper label output and supports image recognition so you can scan and identify 1D/2D codes. You can also convert photos into editable label content directly in the app. App tools include automatic template matching, image recognition and printing, plus customization options to change content and position. Design choices are plentiful with 20+ fonts and 1000+ image materials available. When you purchase from our store you receive the standard return policy and access to customer service — we respond to inquiries and provide support promptly.
