This double walled mug holds approx 12 oz 
Glaze is food safe, the mug is microwave and sishwasher safe.
Though it looks fragile, the mug is intented for typical everyday use!
 
There are 2 of these mugs available, I am putting them in the same listing because they all look fairly similar with slight differences.  Once the two sell out, this listing will say "out of stock"
