We proudly engrave and ship all of our engraved goodies from our shop in Ohio!

Drinks Stay Hot or Cold: Our double-walled, vacuum insulated stainless steel mugs come with an open port lid and will keep your drinks the temperature you want! The standard lids contain a straw friendly open port drinking hole. Sliding lids are available in our options and add ons section. https://www.etsy.com/shop/3cetching/?section_id=26132908 (15oz/20oz Handled Mugs come with sliding lids as standard, the other options all are a standard open port, bottles have a flip top spout)

Engraving is permanent, but it is not recommended for dishwasher use. Please hand wash. We DO NOT use vinyl, decals, or wraps on our mugs! Each is powdercoated for extreme durability! The 20oz and 30oz mugs are narrower at the bottom to fit most standard cup holders.

***NOTE- Designs will be scaled to appropriately fit your desired choice of size. Some designs, if personalization is requested, will be personalized on the back side of the mug due to size restrictions. If you do not want this please let us know before ordering!
