Comfortable to wear. Worked after swimming in the sea. Would be nice to get them in a smaller size too as they might be a bit big on a female wrist. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/82488740-yarongtech-rfid-wrist-bands-125khz-em4100-tk4100-read-only-door](https://www.desertcart.tn/products/82488740-yarongtech-rfid-wrist-bands-125khz-em4100-tk4100-read-only-door) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-10*
