The Wall® teacup is the simplest and cleanest way to infuse tea, herbs and berries in a single cup. The glass cup has a fused glass strainer on the preferred drinking side to act as a filtration barrier to keep the leaves from your mouth allowing for a full, unconstricted infusion to occur.
Each unit is handmade from 100% borosilicate glass (laboratory grade, heat resistant), and has proven to be extremely durable through extensive testing. Because the entire unit is made from the same material, they are fully recyclable as well as dishwasher and microwave safe!
