Bests & Worsts Reviews from Amazon

These are NOT natural bamboo fiber sheets. I could not find a label on the sheets. Only on the packaging. I tie dye and use cellulose fiber reactive dyes. They work with cotton, rayon (which is cellulose based like bamboo). I have dyed many bamboo fiber materials with great success. However when I tried to dye these, they did not take the dye. The sheets are not bamboo, but polyester.
