I bought this as a gag gift for mine and my friends kids and they really are stinky. The rotten tooth is the worst, it's dead on with the smell of a infected tooth. I had to put them in a box by themselves until Christmas but they're definitely what I was looking for I just underestimated the strength. I sincerely feel bad for the workers who do these orders but the kids will get a kick out of them. I'll probably take the old tooth one out though, it's pretty nauseating. I'm considering ordering good smelling ones too lol

I bought these for my daughter. She loves silly things and gag gifts. But these are amazing. They are so strong and smelly. We have them kept in a plastic pencil case box to contain the smell. They are really poignant. She doesn't like using them too much now because of the smells but won't throw them out because she likes to gross others out with them still. They kinda all blend together though with the smell rather than each having their individual smells that they're labeled with.
They make me gag but the kids enjoy them.

When I opened the package PU they really do stink

When it comes to crayons, you just can't beat Crayola. The great quality is always noticeable to me in the crayons as opposed to other brands. My 6-year-old son is obsessed with anything Silly Scents right now. He enjoys collecting the different scents and making us smell them and guess what they are. Plus, he is coloring more which is great. In stores I could only ever find the regular fruity Silly Scents crayons but when I saw these stinky ones, I knew he'd get a kick out of them and purchased them for him for Christmas. Just as I thought, he loves them! These are a fun twist to normal crayons and I hope Crayola keeps creating more Silly Scents.

The scents are:
Mushroom, pizza, onion, barn, old rotten tooth, grass, cheese, socks, moldy sponge, cough syrup, dirty potatoes, and flat tire.

Perfect for the silly boy on your life! I only buy Crayola Twistable crayons because they are durable and can't end up broken little pieces. Crayola has been doing scented crayons, markers and pencils that give coloring an extra level of fun. All of the previous crayons were very pleasant smelling like grape, cotton candy, oranges etc. That is not the case with these!
These are only scents that would be appreciated by little boys! There is nothing pleasant about them! As a whole it smells like stinky garbage! Individually it is worse!

My son was not interested in coloring until we got these stinky crayons. Now he likes to draw pictures and have me smell how terrible they smell!

I think they would make great prank crayons. My son loves them, but my daughter doesn't want them too close to hers because she's again they will ruin her crayons. Not every child is going to appreciate these crayons, but the ones that do will really enjoy them!
