50 unique programming computer stickers. Please refer to the pictures for references of what they look like. There are no duplicate stickers. Overall, this set has an excellent mix of different styles, sizes, colors, and show references. Most stickers are slightly under 3 inches on the longest side. They are made from vinyl and if applied to a clean, smooth surface, will not come off due to rain or other environmental hazards. Being made out of vinyl, these stickers are waterproof and will not be ruined by water. If you are looking for a set with less stickers, check out my other items for smaller lots.
