Vintage new old stock, permanent press percale full flat bedsheet

Enjoy this vintage percale new in package full flat bed sheet. This is a white sheet with bright blue flowers. This is in new condition. It has been stored well, but it does look like it would need to be laundered upon opening. The package is not perfect. On the package it states it’s irregular on the original package. I am not opening it to see what is irregular about it. It is for a 54 x 75“ mattress. It measures 81 x 104 before hemming. It is 50% polyester 50% cotton. It has over 180 threads per square inch. This is per the package. This is cross posted. Enjoy.
