Coffee and tea drinkers unite with our 13 oz. clear glass coffee mug etched with the city streets and neighborhoods of Chicago, IL.
The Chicago mug was a pleasant surprise: much thicker than I expected. I don't think it will break easily. You can see the engraving, but it's no quite as crystal clear as in the photo. I think it would be nicer to have the lines of the map slightly deeper and therefore more prominent. Would buy from here again.
