qarbo CLASSIC - Sparkling Water Maker Cap Silicone Seal (2 pack)
Spare clear silicone seals that go on the inside of the regular qarbo CLASSIC screw top storage caps and the Aircharge Caps.
Sometimes, these seals pop off due to gas pressures. Sometimes, you pick it up in time and put them back in. And sometimes, they get completely lost.
These are for that contingency.
*Caps are not included.
