Laser problems resolved. Back in business.
Navy blue insulated Polar Camel 20 oz tumbler with USNA class of 1971 crest engraved. Shipping is in USPS Medium Flat Rate Box (MFRB) ($15 shipping). I will combine shipping costs if ordered with class pen and/or slate coasters. Two tumblers, four coasters, and pens easily fit in the MFRB. 50% of sales on these will be contributed to Feeding America for COVID relief.
