These are the perfect size to keep your Lionel "O" gauge FasTrack from separating during use. Simply clip on the center portion of the back of tracks where they connect together. No more track separation!
Handy size. They work great for holding about 150 pgs of copy paper. They work well for holding trash can liners on plastic trash cans or bins also good for holding and organizing the small computer wires around the desk and for storage. Think outside the box tons of alternative uses for holding things.
