Excellent quality! I stuck one on my girl's forehead! Now that we have sex... I even in the most tense moments, I can turn on my favorite music on the phone! Thank you.

work exactly as described. Was able to read and write the tag with NFC tools (Android). was able to read it with various phones

The order took a long time, but I did not hurry. Everything is determined and works. And not very expensive.

Very good. Works very well and the glue adhesive is very strong. Came very well packed also.
