I plan on using these for rewards in my classroom. My suggestion is to go through them all FIRST....b/c there may be some that are not classroom-friendly. And those, may be more suited for friends' gifts and such. Otherwise, I'd suggest looking for these amd similar items for classroom rewards, placed in a giant 100's chart. PS... look for misspelled words on stickers, too.My kids love to decorate their school cups and chromebooks. These worked perfect!My third grader bought these to trade with friends at school. they use them on their laptops, binders, & water bottles, etc. more than enough to Go around. They were a great value.Like the other reviews mentioned, there are some stickers that are inappropriate for younger kids (such as "B*tch Spray). Others are kind of questionable, such as "American Teen." As a parent, you have your own discretion, but as an educator you have to be more conscious of what you hand out. The paper backing on some of these stickers did not cover all of the adhesive, so there were stickers stuck together. Preview the stickers before you use them.I should have taken photos but I was quickly pulling out the inappropriate stickers and those with swear words. Was not expecting that! If these are for adults (do any adults use these?) ? then go for it. If for kids, you’ll need to fish through all 300 stickers to remove them.These were very cute and fun. Lots of options in all different sizes.I bought these for my kids (8, 8, 5 yrs old) to decorate their water bottles for school. I did go through them before letting the kids pick out their favorites. There were just a few, 3 or 4 that I didn’t feel was age appropriate. One saying “hella cute”. The stickers overall are super cute and fun & have stayed on their water bottles through hand washings and water refills. No complaints, great quality!Stickers have that paper feeling but kids love them!
