Mighty Mug Go - Stainless Steel - Matte Black - 16 oz

My husband loves these cups for his coffee for work.

This set will make 4 I have purchased, they do a great job with hot and cold retention. I have found that when drinking anything other than water I must wash the tops very thoroughly or else residue start t build up and the mechanism for opening or closing the drinking section over time quits working and requires me to unassemble the spring mechanism.

I bought two as gifts, they loved them. I have owned 2 of my own, great for on the go fun.
