Our towels sets are made with premium woven cotton and terry cloth.  They are machine washable and tumble dry.  Each set comes with 6 towels that are approx. 12" x 12" in size.  They are also fitted with snaps so you can put them on your paper towel holder, or snap around your refrigerator handle ( or anywhere else you'd like!).  Our personal sets have lasted us well over 2 years with all of the countless times we've washed and dried them.
