This is a 'wax resist' mug. The wax part must refer to how it was made? As they have nothing to do with wax. The odd thing about the mug, is that everyone on it is annoyed or mad looking...even Tails, which is uncommon. Sonic looks upset by something, Knuckles seems annoyed and Tails is aggrivated. It's a bit of a shame though because the mug does have good design effort with the base being purposefully shaped like a gold ring. Also, that it has a different character & rings for all sides of the mug so everyone's included is nice as well. It spells their name in Japanese and then in English (small letters) along the bottom. The English font though doesn't look like a good choice because the edges of the letters look worn or almost peeling. This is a winter 2021 item, but where is it sold?
