This is a basic pack of simply colored markers by Tombo. In a clear snap-shut pouch you get green, blue, yellow, red, brown & black markers only. The slip inside the clear pack has Sonic & the logo on the front & pointing SA1 type Sonic on the back. But, notice that each of the markers inside are also branded with the logo & a picture of Sonic. (So, it went the extra mile to not just brand some generic thing with a Sonic insert, they went ahead with quality) From the graphic style, these are likely from around the time of Sonic Adventure 1 or so.
