I chose these protective sheets because they are washable unlike 95% of cover sheets that are found on the market. A little worried at the reception on the resistance to washing I have washed in delicate / silk program with a spin 400 laps and have resisted, but it will some pilling. However, do not withstand repeated washing. 4.60 paid in Cart more when buying so reasonable price. More than 5 I find the price too expensive for what it is.
