Applique Breastfeeding Reminders by Nurserite are designed to be permanently attached to your bra. Each pack includes one applique with Velcoin hook backing, and four iron-on Velcoin loop backs. Each of the four Velcoin backs are ironed onto a bra cup (so each pack contains enough Velcoins for two bras). The applique attaches by its Velcoin hook to the Velcoin backs on the bra. The Velcoins will last through many bra lauderings.
