30PCS NFC Tags Black NFC Cards 25mm(1 Inch) Coin NFC Card Compatible with TagMo and Amiibo, 504 Bytes Memory Work Perfectly with TagMo Amiibo and All NFC-Enabled Cell Phones & Devices

Easy too use, size lines up with business card, was able to use nfc app no problem. Write/rewrite easily. They didn't take HTV vinyl from my cricut & did get a little warped. But still worked! Will buy again.

Firstly somehow these were at my doorstep the day after I ordered them! (I used free shipping, and don't have prime) I haven't tested all the tags yet but all 100 were present, and the ones I have used so far have worked perfectly with Tagmo for amiibo spoofing (or backing up/cloning game data from real amiibos). They're light, and thin but feel sturdy. I chose the 1-inch circular size for versatility. I could put it in a coin case later, sew it into a piece of fabric, maybe even put it in a jewelry pendant!!
