I do not remember where I bought this, but I would like to buy something
similar.

It is about 14.5 x 16.5 inches and is made of plain white cotton.

Replacement can be +/- a couple of inches of both dimensions.

I did a search for

"white towel" and various dimensions but only found bath type towels or
disposable ones.

Try hand towel.
