Frisch’s Big Boy ROOT BEER MUG From the American restaurant "Big Boy" This is a large plastic travel mug. The lid has a hole for a straw. 【Size】Top diameter: approx. 9cm, Height: approx. 15cm This is a USED item with little use. * Although there isn't much sign of use, there are some minor scratches. I purchased it at an antique mall and have displayed it without ever using it.
