Our review
The Nelko P21 is a pocket-sized Bluetooth label maker that connects to your phone and prints thermal labels in seconds — no ink, no toner, no computer needed. 23,000+ reviews at 4.5 stars. Perfect for the person who wants every jar, bin, and cable labelled.
The companion app has 3,600+ icons, 750+ templates, and 29 languages. Print text, QR codes, barcodes, or custom images. Thermal printing means no ink to replace — ever. USB-C rechargeable battery. The device is genuinely tiny — fits in a pocket or drawer without taking up space.
Teachers love it for classroom organisation. A reviewer who just turned 30 calls it his 'transition into adulthood' gadget. Multiple parents use it to label everything from lunchboxes to storage bins. One reviewer says setup takes under 2 minutes. 77% five-star.
The downsides: 6% one-star — labels can jam and need realigning. Some app fonts are locked behind a subscription. Not compatible with computers (phone-only). And the labels are fixed sizes — no continuous roll option. But at ~$21 for a label maker that turns phone-to-label in seconds, this is the organisation tool that makes you actually want to label things.

How do I design labels?
Download the free 'Nelko' app. Connect via Bluetooth. Choose a template or create from scratch with text, icons, QR codes, barcodes, or images.
What can I label with it?
Everything: pantry jars, storage bins, cables, lunchboxes, classroom materials, office supplies, cosmetics, mailings. The thermal labels stick to most smooth surfaces.
