Instant purchase is welcome, no need to comment. This is a mug purchased at Flying Tiger. The box states that the color changes when you pour a drink (I haven't confirmed this as it's unused). Although it's a new item, the box has some damage, so please refrain from purchasing if you are sensitive to this or if you are looking for a perfect item. I will wrap it in bubble wrap and take measures to prevent water damage before shipping. I am selling many Flying Tiger items. #DeclutteringAndBecomingAMinimalistFlyingTiger Flying Tiger Copenhagen flyingtiger flyingtigerCopenhagen mug
