Cases can be hand-washed in warm water like our straw buddies. Straws are BPA free and dishwasher safe!
The case is not meant to be completely waterproof but the lid is tight enough that a little liquid leftover on the straws after use will stay in the case and not get all over you bag! They measure about 3 inches tall and 2 inches wide.
(Straw Buddies do not fit in this case and are not included)
