TOA70.5"x30"- 50 Sheets/Roll Disposable Poly Paper Waterproof Exam Massage Table Bed Cover 1 Roll

Does it look and feel like wax paper? I'm trying to find extra wide wax paper and this is the closest thing I've come across. Not for cooking.

would this work for the smaller than twin size bed in the nurse's station at my church.

It's not the intended purpose, but can you write on this paper (with pens or markers)?

How many rolls?
