Great product, very poor shipping.
Very disappointed in the shipping, the wash and wax leaked all over the rest of the products inside. Have to wash the towels due to them being full of soap. Great products, adds shine and water beading slickness.

Make sure delivery is not with USPS
Color: 6pcs
Product is good quality. The delivery service is the issue. No one should the USPS for anything but junk. Worthless tax payers money paying for the wages of employees who don't want to work at a government business losing billions of dollars a year.
