Card collectors, this 6-pack of storage boxes is exactly what you need to keep your collection organized! These Woodhaven Trading Firm boxes hold about 400 cards each (more precisely, around 350 standard 20pt trading cards or up to 560 thinner gaming cards). The design has been recently improved with extended inside flaps and tighter tuck notches, so the boxes actually stay together properly without that annoying side slippage that cheaper boxes have. They're plain white without any logos, which looks really clean and professional when stacked up. Each box measures 7 7/8” long by 4” wide by 2 7/8” high on the outside, with interior dimensions of 7 1/8” by 3 7/8” by 2 3/4” - perfect for standard sized cards. The best part? You don't need any tape or glue to assemble them - they just fold together securely. While they're designed for trading cards (baseball, basketball, football, hockey, MTG, you name it), they're also handy for storing all sorts of small items like tools, parts, or glassware. Buying manufacturer direct means you're getting quality boxes without the middleman markup!
