Card sleeves help keep standard-size trading cards organised during storage, play and collection sorting. The clear format lets you view card details without removing each sleeve, while the 2.5 x 3.5 inch fit suits many commonly sized cards. Designed for collectors, players and children aged 3 years and above, these sleeves are useful at home, in classrooms, during game sessions or when arranging a card album. Adult supervision is recommended for younger users. Each sleeve is made from flexible polypropylene and provides a separate layer between cards. Compared with loose card storage, individual sleeves help reduce contact, surface scuffs and stain exposure. They are flexible sleeves rather than rigid holders, so use a rigid holder separately when extra structure is needed. Insert one dry card at a time with clean hands. Keep the sleeves away from sharp edges, moisture and excessive heat. Store sleeved cards flat or upright in a suitable container, and replace any sleeve that becomes creased or damaged.
