Set of four 4″ by 4″ slate coasters with USNA72 class crest laser engraved on them. Rubber pads on bottom of coasters to protect furniture. These will ship in a USPS small flat rate box. If purchased with a pen, I will refund $10 postage. Please note: I have the class crests on file for all classes from 1967 to the present, and can also engrave them on coasters and pens. Will combine shipping costs if ordered with a tumbler(s). $12 per set donated to the Navy Marine Corps Relief Society.
