Another Boom slogan tee, this time it's "Witness my Quickness!". This all blue tee has CG '3 point stance' Sonic on a sort of 'energy swirls' also blue background. The slogan is large, with white and blue swirling through the text. Compared to other Boom items, this one's fairly plain, but the large Sonic graphic & fun slogan come together to make it stand out enough. The tee is all cotton, and is 'boys-teens' sizes, so it's likely to fit most. Note the lack of tag in the collar, but it's known to be made by Bio World, and where can you find it? It's a fall 2017 item.
