This French press tumbler has an advanced filter design that stops any coffee grounds or tea leaves from escaping into your drink.
Once depressed, the filter automatically separates and isolates the tea leaves or coffee grounds so that the brewing process ceases and prevents degradation of the flavor.
Double walled stainless steel vacuum and insulated tumbler will keep your beverages hot or cold for 4-6 hours.
BPA, BPS, and Phthalate free.
