ATC 1 5/8" Medium Crystal Clear Hinged Storage Box w/ Snap Closure. Brand new ATC Crystal Clear Plastic Hinged Box that snaps closed. This is great for protecting your ATCs from dust and liquid spills. Great for transporting your ATCs when traveling and going to workshops. This box can hold up to 50 Artist Trading Cards, but can hold more if they are thin ATCs. Originally, this box was made to hold 100 trading cards. ie. baseball cards, but what a great storage box for us ATCers. The outside measures 2 5/8 in. x 3 5/8 in. x 1 7/8 in. The inside measures 2 1/2 in. x 3 1/2 in. x 1 5/8 in. The photo just shows one of my ATCs that I made; it was hard to show the box 3 dimensionally.
