Worked perfectly!

Nice and soft and tough. I've never used this before and it came out so well. Was like a soft mattress topper feel.

Great for making squishies

Buying squishies and repainting them or buying unpainted ones and painting them yourself is cool, but making your own is even better. I use silicone baking molds, candy molds and ice molds to cast mine and have had great results. This starter package will make a LOT of squishies. It is easy and the company's web site has great videos explaining everything. BE SURE to pick up lots of paint stirring sticks at some place that sells house paint because you will need them. This is great stuff an easy to use. Just know that once you mix the two parts (A & B) together you have have 30 seconds of so to get it in the molds. This is very different from acrylic casting which has a much longer pot life.

Read directions

Needs to be done in a warmer environment and be sure you mix it plenty before you pour it in. When I did it right it worked great. The only problem I had was not doing exactly as the directions said

Please read!!!!!!

This is not for the faint of heart. It is toxic and very very unforgiving. Please watch YouTube videos and read their site for help.It’s insanely sticky, so use silicon forms where you’re pouring.Measure!!! Use a scale, it makes it so much easier. 1A:2B or .575 difference. 10 grams A = 17.3g B. This is insanely important. Very unforgiving. Yellow bottle is the hardener…. Too much yellow it’s too hard or doesn’t expand. Too much blue bottle it doesn’t stay expanded and looks weird.Mix until 35 seconds and your shoulder is on fire. When you combine the chemicals after measuring exactly, mix immediately and use a timer. Mix until your shoulder burns. Really really really mix. Minimum 35 seconds, then pour.Lastly, it doesn’t like cold. Has to be 72+ or it doesn’t fully expand. This is all listed on the website and 100% accurate.Measure - mix - warm - remove after 25 min.It’s a great product and has a lot of uses if you can do the above.

Amazing

What I liked is this product did exactly what I was hoping it would do. What I didn't like was that you have to work very fast because of how fast it sets up. It just means you have to be very organized before you mix the product. I used this product on a vintage car steering wheel horn pad that the original foam had split and separated from the horn pads structure.

Short shelf life

Ive used small amounts thoughout the year and have noticed that one part has thickened considerably. Its been a year and now when measured and mixed properly it will not cure. Was stored in a refrigerator at 40°f and allowed to come to room temp before measuring/mixing each use.Also was softer foam upon curing than i was looking for. This is in the Shore A or B range. I wanted something in Shore D.

YAY SQUISHIES!!!!!!!!

So my 9 yr old is all about squishies. This product was very very easy to use. However I will warn u. Def wear gloves. And don't let it get on counters, sinks etc. very hard to remove. Also I saw in other reviews to get quick release. I didn't get that and it was very hard to get out of silicone molds. Also when we did it in a plastic container or cup it didn't stick as bad and bottom came out much smoother then silicone molds. The only thing I did have trouble with was the measuring part. Didn't understand the measurements that came with it. So it was a lot of trial and error. Also when we closed containers the B container got stuck like crazy glue stuck. So it's very fun craft to do with ur kids. Just needs better instructions on how to use. I will definitely buy again

Fun and Functional, But You Better Be Quick!

I poured this into a silicone cupcake mold and it quickly puffed up and set into a very pleasing squishy. The only problem I had was that it foamed up a lot, and fast, and I had some bubbles in my squishy at the bottom of the mold, which was of course, the top of my squishy. So next time I am going to try Flex Foam It! 6 or so for the slightly denser foam, and hopefully I won't have the bubbles...

Great - works really well

This is a great product. Slightly scary instructions but we found that there were minimal fumes etc. We've made a number of squishies using this. The only trouble is finding suitable moulds to make them from.

This kit is the bomb

We have made foam toys with this kit and its fantastic. Does exactly as promised. 2 polymers combining in a chemical reaction to make a squishy toy.Be careful and adhere to the safety instructions.

Great product, great customer service.

Wear gloves! ( I was dumb, chemical burns ) But the customer service of this company is outstanding. ( got a call on Christmas morning by the ceo to check in even though I made the mistake ) Great product, worked perfectly - ***read all instructions carefully and follow them. ***Do not follow youtube tutorials.*** This product has the correct detailed instructions inside!
