Review of Fluidproof Fitted Sheet – Black by Phillip C. on 29th November 2020 with No Comments Review of Fluidproof Fitted Sheet - Black Posted by Phillip C. Sheets of San Francisco hit it out of the park. Extremely durable, machine-washable, and lots of fun included. The customer service is phenomenal and quick. I wish I had more beds to fit with these sheets + pillow cases. 10/10 would recommend!!!
