### ⭐⭐⭐⭐⭐ Review
*by H***E on 4 February 2019*

I just got this mug in the mail and it is going to be a cute gift for our granddaughter who turns 18 in a few weeks. I bought a separate 18th birthday inspirational keychain and placed it inside the mug. The mug is shipped in a sturdy cardboard box and arrived without damage within 5 days of ordering. That is a good time frame for an Amazon Prime customer residing in Hawaii as we often have to wait up to 3 weeks to get orders outside the continental US. The mug is only 11 oz. in size so holds about 10 oz. once you fill it with a hot liquid, but it's a very cute mug and a nice gift to go along with J's favorite Hawaiian treats we will ship inside her much coveted birthday care package.
