HELPER: Corner pockets have a feature called "thumb cut" on the side, which allows for easy opening of the pockets. Access to documents is easier and quicker. MATERIAL: The material of corner pockets is grainy polypropylene, meaning it has a granular appearance. This aspect is anti-glare and provides visual comfort during use. RESISTANCE: Corner pockets are made of grainy polypropylene (not smooth). This grain provides better durability as it resists marks and stains. TRANSPARENCY: Corner pockets, despite their grainy appearance, are translucent. This transparency allows for quick access to information and immediate identification of the contents.
