“I bought these in white and black for some steel cups that had broken plastic lids. The plastic had broken because I put hot liquids in the steel mugs and the heat was too much for the rigid plastic that came with the steel cups. The Silipint lids fit perfectly and stand up to hot black coffee and tea. The spout allows you to drink coffee/tea in the car without risk of spillage. These lids make it possible to use steel mugs that otherwise would have been useless.”
