This is a 12 oz ceramic "MD" Maryland travel mug produced by Starbucks. It comes with a black lid.

Very good condition. There is a small light sparkly line, measuring approximately 0.5 inches between two of the crabs (see picture). It is the same color as the crabs, so I don't know if it is a manufacturing defect or something else. It did not  come off with minor cleaning efforts. Otherwise, the mug is in great shape with minimal wear-- there are no chips, cracks, or other damages. Nice overall.

See pictures for more details.

If you have any questions, please let me know. Thanks for looking!
