Crystal clear top loaders measure 3 inches by 4 inches. High impact rigid plastic, archival safe for original art and trading cards. Package of 25. Will safely hold a 2-1/2 by 3-1/2 inch card enclosed in a polypropylene sleeve with no problems. It is highly recommended that polypropylene sleeves (also known as Penny Sleeves, poly sleeves, Soft Sleeves) be used for original art as well as the Top Loaders, as this practice will prevent any media that is tacky or not yet fully cured from sticking to the Top Loader. Top Loaders work great for safe shipping or for storage for ACEO cards, ATC cards and Sketch Cards.
