Attention card collectors! If you're serious about protecting your valuable trading cards, this 500-count sleeve set is exactly what you need. We're giving you a massive collection of protective sleeves in five awesome colors - cyan, purple, orange, mint, and yellow - so you can organize your collection in style while keeping everything safe. Each sleeve has a clever dual-side design: one side is glossy and crystal clear so you can easily see your card's artwork and information, while the other side has a matte finish that helps protect against scratches and keeps private information... well, private! The material is high-quality non-PVC polypropylene that's completely acid-free, so you don't have to worry about your cards getting damaged over time. These fit standard-sized cards perfectly at 66x91mm - think baseball cards, football cards, MTG cards, gaming cards, proxy cards, even small photos. They're not too tight that you struggle to get cards in, but secure enough that your cards won't randomly fall out. With 500 sleeves total (that's 100 of each color), you'll have plenty to protect your entire collection with some left over for new additions. This makes an amazing gift for any card collector in your life, or just treat yourself to some serious card protection. We're here to help if you have any questions - happy collecting!
