A little creepy and serene. They are a heavy cardstock/thin cardboard. Sturdy enough not to flop over and are not flexible. No adhesive on the back. 8 pieces. These cards measure approx. 3 3/8 x 2 1/4 inches. I have more stickers, washi tape and paper for sale. If you would like to purchase multiple items please put all the items in the cart and then pay. I do combine shipping and I will refund you the difference in shipping after payment is made. Sorry, eBay will not allow buyers to request a total from sellers with immediate payment. Let me know if you have any questions through eBay messaging. Thank you for stopping by!
