Wamsutta 1970s pastel rainbow striped twin flat sheet

Incredibly rare Wamsutta 1970s pastel Superscale rainbow striped twin flat sheet. They honestly don’t make sheets like these used to. This is 50+ years old and still in amazing condition!! Colors still vibrant. Polyester and cotton. Outstanding condition. Has a faint dust/mildew smell just from the age of them, so could use a washing with some vinegar and scent booster.
