This back pack looks similar to the set found here...
But it is different, as it is a "Toddler Backpack", and is only 12 inches high.
For very little kids, a smaller school bag is probably an ok idea, especially if it has a nice Sonic design like this one. You've got the glossy Sonic face for the small pocket at the top & a nice design on the larger square pocket with Shadow, Knuckles, and Tails. (Oddly, Shadow seems to be the star here) Then, the top of the bag (where the main pocket zipper is) has checkering. The side pocket is nice too, one has the usual mesh, while the other has a velcro flap-over with the logo on the flap, and an extra Sonic face on the pocket part. The back straps are the usual red, and the carry handle is blue nylon. Nicely designed with plenty of Sonic elements, it should be about 18 dollars & is confirmed at Amazon...and anywhere else?
