I believe it was this pack of stickers. Most of them are skateboarding/clothing brands. These are the ones I couldn't figure out. Some of them might just be art, but a few look like logos.

Also, if anyone has any idea as to what to do with 100 stickers, I'd love to hear your suggestions.

Couldn't you check your order history to see what pack it is? Or did you order multiple packs?
