This glove's ability is Opposite Day, which is an active ability that makes it so that any slap you receive will be reflected onto the attacker instead of you for 6 seconds. The glove's texture is a yellow UNO! Reverse card. It costs 5,500 and is required to get the potato glove, The Reverse Incident badge, and access to The Ruins to get the Recall and Psycho gloves (unless you use the reverse ability from Mitten's presents for these badges/gloves).
Reverse was added in Slap Battles on Augand is a slap-costing glove in the game.
