Culture Tumblers are ready to go and will keep you hydrated with its 40oz of freedom capacity, stainless steel for hot or cold beverages and a reusable straw.
The lid has 2 different openings for sipping with or without your straw.
We won’t promote this as spill-proof but we will say it does a good job of keeping liquids mostly inside our tumbler if it does fall over ;)
Happy slurping ;)
