A Sonic Christmas Ornament?
It's true, and it's actually the 2nd one to exist. (The first was that 'game gear tiny system model with Sonic in the fake screen) This is a 3 inch diameter printed ceramic ornament. It is flat, with a hole at the top for a hook or ribbon to hang it on your tree. Oddly, the ornament isn't a very 'Christmas' green, it's more surgical-scrubs blueish-green. One side has a new/specific for it (which is nice) art of classic Sonic in a Santa hat, holding 1 gift while walking, as other gifts are in the air around him. The other side has a 'holiday sweater' like pattern & the phrase "Christmas Greetings From Sonic" with the last bit in script-ish font. This is a Segashop exclusive item & is 16.95. That's a bit costly because it is so small & doesn't even come with something to hang it from a tree.

This is an item for the holidays in 2018, but it appears in January. (So, getting ready early) But at nearly 20 dollars for a tiny 3 inch item...(and you can guess printing on some ceramic disk isn't that costly) and it seems a more than a little 'out there' on the pricing. Plus, if it's ceramic, its' fragile too. Why not make it on metal for the same price?
