Toy Island produced a set of Sonic Adventure 1 themed pencil toppers. Each plastic topper is a fully 3D figure of the character. As you can see here, they also came already installed on the tops of pencils. Each pencil has the same theme: a scene from Sonic Adventure. You can see they have Sonic, Eggman, Knuckles, Big the Cat, Tails & a neutral chao.
Notice that they did a good job with the figures. Everyone is pretty on-model and proportionate. Big's body is kind of small, but he still looks ok. 

Notice how none of these are "Actual Photos" of the items.
They are all stock photos taken by Toy Island. They were advertised on the back of the "Sonic Gel Pen Set" and other related items...like for example the pencil toppers would likely have photos of everything else but themselves printed onto their box back as a way of advertising all there was to collect at the time.
Due to this fact, you can't tell if items like the scissors were individually packed, or you got all at once. It also can't be proven if everything here was released or not. Likelyhood of release is VERY GOOD because several of the things (3D erasers) have been found by fans. The release was probably pretty poor though, as items like this are always popular with collectors and fans, generally inexpensive/easy to access...yet, here in 2015 there are no fan photos.
