You know what generally feels (and tastes) better than a whole bunch of complicated feelings? Yep, it's tacos. Preferably accompanied by several margaritas... just in case some of those pesky feelings try to come peeking through.
Vintage reproduction enamel mugs are made from a thick enamel-coated steel. They are heavy (for enamel mugs-- still lighter than ceramic), smooth, wonderful to drink from, and crazy sturdy. You can abuse the heck out of them.
MICROWAVE & DISHWASHER USE:
These are steel under enamel. So please don't use them in the microwave unless you want to create a localized lightning storm in your kitchen and pretend you're Harry Potter. Or Voldemort.
