cotton or bamboo [SEP] for diy face masques these are not quite as good as i hoped but better than i expected they come in a little compressed tablet about the size and shape on an antacid tablet but grow when liquid is added they are a bit hard to unfold but once unfolded they are a generous size however they lose a point because the product page in one place says they are made of cotton and in another says they are made of bamboo these are made in china and there is no clarification on the package that i can find so i do not have a clue what these are made ofthey are not quite as soft as the ones that come with their own serum that i have tried but they are fairly sturdy you can rip them if you start ripping in a corner but they do not rip as easily as i would have thoughtso these are acceptable dry face masques but their product page and labeling needs some improvement
