DIY Molding and Casting Set Smooth-On Silicone Mold Making Liquid Rubber OOMOO 30 with Mixing Supplies Kit

Just don't buy from this seller. Smooth-on is great and I have used this product before but I am pretty certain this seller does not know how to properly store this product or doesn't sell it fast enough and it goes bad on the shelf. Pretty much, the substance in the yellow bottle was completely solid and useless. There was no way to mix it with the blue bottle which was also half solid. The bottom half of the liquid in the blue bottle was solid. Just see the picture.

The product is exactly what i expected

both the blue and the yellow containers were hard as a rock when I had gotten them.this is the 2nd time I've ordered this product and both times they were hard and not useable.

The yellow bottle had solidified a great deal, and I should have packaged it back up immediately and sent it back, but I didn’t. It made the two, almost, impossible to mix thoroughly and took 20-25 of the 30min pot time to get anywhere near mixed, which caused the mixture to not pour fluidly and render the mold made with it, unusable. That’s $50 I’m never going to see again.

I have ordered this product TWICE and both had to be returned because the part A was solid rubber.
