Thermal Coffee Cups 400ML - ZDZDZ Insulated Coffee Mug with Lid & Handle,Stainless Steel Thermal Mug for Cold & Hot Drinks (Black)

Cup is sturdy, would have a hard job to leak as the air hole isnt very big and we've drilled out hole to let air in for the cup to free flow when drunk from. As for Thermal, drink is cold with 20 minutes. Good curved handle

I was getting fed up with making coffee for my husband who is working from home and forgets to drink the numerous coffees I make for him……..no more!
