Here are 2 face erasers. These are the flat, shaped erasers that are made from cutting a long tube of material into slices. As you can see here, they're a good quality, because they are thick. They're also fairly large, look at theri size as compared to the pencils in the photo to the left. It looks like they came by themselves, in some kind of 2-pack with a logo in the middle.

The Tails looks odd because the eyes are too high. They should be placed right at the edge of the lower-face-white area like how Sonic's are. But also notice they did catch the white between the hairs of his bangs...which makes that glaring eye mistake even wierder thing to mess up on.
The left photo shows items from other school supply packs, like the Sonic & Tails white pencils, the STK pearly finish white pencil (came in a pack too, seen elsewhere on gear) and the HB red pencils which had character names on them. There's a Dr. Eggman, and then...."Emmy"? That's right, in the VERY early days you could get Amy Rose spelled as Emmy Rose because the Japanese letter that starts her name just goes "Eeh", (kind of) and there isn't a letter for "Aaayy" to make it specific when converting it into English letters. (Why not mess up Eggman too then? He couldn't, because he's literally 2 pre-existing words & not just a regular human name.)
