[37x47MM] Meowcafe Premium CPP Card Sleeve for Mini ID Card | Kpop Photocard Sleeve

CPP and PP are made of the same raw material but with different manufacturing techniques.

• Both CPP and PP are PVC-Free and Acid-Free
• CPP is stronger, here is why: the process to manufacture CPP requires the polymer to have a higher density and strength to withstand being pulled from different directions which makes it more tear-resistant
• CPP Sleeve is harder, so make it a bit not as smooth to slide in the card, but once the card is in, it provides more protection
