Duct Tape

Appearance
A small round roll of white/silver duct tape with a black tube in the center. It's assumed that the duct tape now has magical properties based on the sparkles around it (similar to the ones that accompany Steven's magical spit), along with Greg's wink and suggestion to Steven, "Just in case you have trouble again".

History

 * Duct tape was invented during world war 2.

"House Guest"
Greg Universe tries to use it to fix his van along with his leg, expressing that "Some well place duct tape can patch up anything in a pinch." Later in the episode, he, along with the help of Steven's magical healing spit, manages to seal the geode with more duct tape.
