We recommend you hand wash our mugs, and do not place in the microwave or dishwasher, so as to preserve the vinyl design. We ship all items within 5 business days. Mug sizes/styles may vary depending on availability. All mugs will at least be a minimum of 12 oz. If you have something special you would like...Message me!! We would love to bring your creation to life. :) For larger orders - please message me for a shipping quote. It may end up a lot cheaper than just selecting a higher quantity when checking out. I can then set up a custom listing for you.
