Lid For Carabiner Steel Mug

To use with our Stainless Steel Carabiner Mugs. We have a lid with a rubber seal and a ball chain to fix it to the cup so that it never gets lost. This way, you are sure not to spill a drink. Perfect protection against confetti and secondly, it closes the cup securely and tightly, so no one can put anaesthetic drops into the drink unnoticed.
