A nice inexpensive addition to the can shaped glass, the bamboo lid has a straw hole and comes with a straight clear glass straw. The round natural bamboo wood lid helps prevent spills and looks super cute. With a diameter of 70 mm, it fits our beer can-shaped glasses. The lid add-on is a cheap, fun way to enhance the drinking glass making it a fabulous, well-rounded gift idea perfect for friends or family members who are always on the go.
