<br>Use heart stickers as wedding invitation seals, Valentine parties, scrap-booking and thank you cards. They are the perfect way to make your day happier and brighter. Our 3/4" purple heart stickers are made with a semi gloss paper material and has a standard permanent adhesive.</br><br>These labels can still remove from most surfaces but they do have a strong adhesive backing. They are also apparel safe, meaning they will not harm clothing. The 3/4" measurement is from highest point to bottom point. To give an idea, they are the size of a penny. There are 500 purple hearts on a roll. We do add about 20-30 extra to make up for the tape to hold roll together.</br>
