These tumblers are HUGE in both popularity and size!!
 
The lids screw on and the cups are made to fit in a cup holder with a 7.5cm base. They are huge, hold 40oz and will keep your drinks hot or cold all day long! The lids twist to use with a straw or to expose the sip style hole. Each cup comes in its own box and includes a straw.
 
These are double walled insulated stainless steel tumblers and are available in 5 fun colours.
