Clasp Envelopes 10x13 size - heavyweight! 100+ in the box

I bought this giant box (don’t ask my why now?!😜) & only used abt 25 for a project. So over 100 count heavyweight clasp envelopes remain in the box. Brown color. Ideal for secure mailing. Please note last pic shows slight mark on front due to moisture rusting the clasp a bit & envelopes are stacked in the box.
