The charms are printed on acrylic, and are extremely durable. They make cute little collectibles, where you can also attach them to your bags and phones!
Once received, you will see a plastic, matte-like texture, covering both the front and back of the charm. You can peel them off, and your charm will be shiny and ready! Those stickers are there to prevent any scratches before purchase, that way you can always assure that my charms are always in good quality!
