HEALTHY AND DURABLE GLASSWARE 
Why is there a small hole on the bottom of the mug?
That small hole is normal for double wall glass mugs. It is part of the manufacturing process and does not mean the mug is damaged or defective.
Do these mugs stay comfortable to hold with hot coffee inside?
Yes. The double wall design helps reduce heat transfer, so the outside stays more comfortable to hold than a regular single-wall glass mug.
Do these mugs feel delicate?
They are made from glass and have a lightweight double wall design, so they should be handled with normal care like other glass mugs.
Can these mugs be cleaned in the dishwasher?
They are designed for convenient daily use, but for best long-term care, many customers prefer gentle cleaning and careful handling.
Would these make a nice gift?
Yes. Their clean modern look and everyday usefulness make them a thoughtful gift for coffee lovers, tea lovers, birthdays, housewarmings, or holidays.
