Each bracelet is handmade with care by a survivor of human trafficking in the Dominican Republic. These bracelets are adjustable from 4" to 9" and come in a variety of colors as well as ropes and chains. In the center of each clay tag is an NFC chip that allows you to tap with your phone to receive a new Bible verse and prayer everyday. No app is required, just tap and hold your phone on the tag for a couple of seconds and open the notification on your phone. Tap To Pray works with most smartphones.
