Very fun product
This arrived well package from the seller and a new condition as expected My kids loved doing this if is fun and exciting, but it is not like the soft gummies that you buy in the store it has a firmer texture and a different flavor but that is part of the fun because you can use the different ingredients to make it turn out differently and have it as a learning experience. I would recommend this product but just let your kids know that it's going to turn out differently depending on how much of each ingredient you add so they know to expect it to not taste like the packaged gummy candy!

Giftable

Fun activity but not very tasty
This was a Christmas gift for my child who is almost 3. He really loves helping me cook and do things in the kitchen so I thought he'd enjoy this activity for us to do together. He did have fun doing it but the outcome for the gunmies was not great. They tasted fine, not awesome but not gross. But I feel like they never fully dried or set up on the outside. By the end of the day we made them whether they were in the fridge or not, they turned into a runny goo and the outside of the gummy was always slimy and sticky. The sour powder wasn't really sour either. Overall it was worth it to just have fun doing am activity with my kid but I wouldn't buy it again

MOMS, THIS ACTUALLY WORKS <3
Follow the instructions and add more water if you must but do so slowly! Our Gummies came out great, and the sour powder was tangy/sweet!

Good and Gross
Nothing is quite as fun as making a disgusting creature and eating it. Not the real thing, but a candy version. A great value for the price, this creature feature is fun, educational, and, well… tasty. Perfect for the 8-10 year old age range.

Would not recommend
Something that should have been simple was massively over complicated. The measurements provided are not correct. The gelatin or “seaweed” mixture that needed to be measured in tablespoons came in a solid block that couldnt even be broken into chunks for measuring with a meat mallet. The instructions were long and repeated the same common sense safety precautions multiple times. Would not recommend. You’d be better off getting your own mold and looking up a simple gummy recipe, probably cheaper too.

It was a hit with the kids
My grand kids thought this was perfect. They had so much fun with it. I bought it for my 7 year old grand daughter but the 3 year old grandson went crazy over it. He "helped" make the gummy candy and loved eating the "bugs."

Insultant! Vraiment! Pour le prix , les friandises reviennent à $2 l'unité! La texture est désagréable. Le pire, c'est que l'emballage ne contient que les ingrédients pour une seule expérience. Après, celle-ci, reste seulement les 2 moules à bonbons. Cher payé! Je vous recommande d'acheter des petits moules à bonbons et de trouver une recette sur internet! Vos friandises seront meilleures. Je ne recommande absolument pas.
