New Item!  Instead of using a cardboard sleeve, some cart manufacturers used a clip on plastic dust cover to protect the exposed tape when not in use.  These clip onto the front part of the cartridge where the pinch roller and pads are.   These work on 8 track tapes, 4 track tapes and most Muntz Carts. 
 
Sturdy black plastic, textured on both sides.  These are brand new and manufactured in the USA.
