Coin collectors, this 300-pack of Ciieeo coin capsules is perfect for protecting your valuable coins! The 21mm inner diameter is ideal for various coin sizes, and the clear plastic design lets you display your coins while keeping them safe from oxidation and damage. Each capsule measures about 2.5x2.5x0.5cm, providing a snug fit that prevents coins from sliding around or getting scratched. The transparent material shows off both sides of your coins beautifully, making them great for display collections. They're particularly popular for games like Quacks of Quedlinburg, but work equally well for actual coin collecting. The plastic is durable enough to protect against handling damage while being lightweight for storage and transport. The snap-tight closure keeps coins securely enclosed without risk of accidental opening. Having 300 capsules means you can protect your entire collection or have plenty for future acquisitions. They're also useful for organizing other small collectibles, tokens, or medallions. The quality is consistent across all capsules, with clear, distortion-free plastic that doesn't yellow over time. Whether you're a serious numismatist or just starting your collection, these affordable protectors help maintain your coins' condition and value. They stack neatly for storage and make handling your collection much safer. For the price, you're getting serious value compared to buying smaller quantities elsewhere. Your coins will thank you for the protection!
