They don't say what material they are made of except for one. This one says that it's made of 65% viscose and 35% metallis. But they are definitely metallic in color. Sorry I couldn't be any more help to you. Thank you for asking :)
no but I am a seamstress and crafter. These are from an estate auction and they came in a sewing lot. But I dont think I'll have use for these, so Im sending them to someone who can use them. ;)
