The third item from this same mystery manufacturer!
It is likely KellyToy that is making these sporting items. Can it be confirmed?
This pair of boxing gloves is actually pretty cool. They're quite detailed with fitting Sonic imagry, including *Super Sonic*! He appears on the front of the fist, while a lesser-seen modern era Sonic is jumping in front of a star background on the thumbs. The cuffs have blue tone checkers, a star with the logo and a line of rings. SS is even named on them, with 'super' added in a different font to the old-style Sonic logo. Surrounded with a ring of stars, the design is very dynamic looking. This is quite a well put-together looking sporting good...great for collecting, and especially stylish with the nice rendition of SS...IF you can find them. Likely released fall 2009, and was available at TJ Maxx.

These checkered-top Sporting good items are being made by KellyToy (also makes Sonic plushes) They may be available at some Marshalls stores in the USA. However, Marshalls is a clearing store which usually obtains overstock from other stores. TJ Maxx closes out as well! Where were/are these initially? Info by JordanJ and also by Sweet_Vegas94
