Wow! Eggman fans can get Eggcited for this one!
It's an Eggman SOLO item! Sonic's no-where to be found, so the bad genius is having a good time here in the Green Hill Zone scene. Solo Eggman items are very uncommonly made, so this is a great collectible, egg-fan or not. This is described as "A canvas wallet", but it's likely not actual canvas but the nylon tough-woven fabric. (Write in if you own this to clear it up) The wallet has an all-over 8-bit look Green Hill scene, complete with the 'goal sign' at the end, which is faced to the Eggman side (naturally) It has a big, flashy arms-crossed/point neoclassic Eggman art on the front and his slogan "Think you can beat me?"

The interior has slots for credit cards and area for dollar bills. This is a 2018 item, probably a Sega Shop exclusive. It could be around 18.00.
