Spare blowout discs for your DDKit.

• Stiff Mylar material breaks cleanly

• 50pc/pack

• Cheap!

• Works with propane and HFC134a

• Comes in handy plastic bag that is too small for your kid brother to fit over his head. Caution: mushed up bag may represent a choking hazard. Keep out of small children.

• Elementary school teachers: DDKit stickers can also be used as apathy "smiley face" stickers  for rewarding B- assignments.

• What else can we say? They're boring plastic stickers that are clear and go BANG when you apply pressurized gas to them.
