UV resistant sleeve made based on the verification test. Although it is a clear type with high transparency, it protects important card assets by cutting about 80-90% of ultraviolet rays (UV-A / B) that cause deterioration. The inner sleeve is the perfect size for your card, so you can use it with other sleeves.
