The materials we use, in plain words
The shop · 1/21/1970

Material names on a product page usually say nothing. Here is what ours actually mean.
Cotton
Soft, breathable, and it shrinks on the first wash — which is why we cut with that allowance already in. Wash at 30°C and it keeps its size for years.
Beech
Hard enough for a handle, light enough to hold all day. It darkens with use. That is not wear, it is the wood oxidising.
Borosilicate glass
Takes a jump from fridge to boiling water without cracking. It still breaks if you drop it.
