Good quality. Bubbles are almost noon existent, and when if there is bubbles, they disapate on their own. Easy to use, just a little hard to pour at first because of the bottle shape. It ran down the side a bit. Cured just fine, I left overnight. The thickens is perfect, soft and pliable. Clear enough to use UV resin without issue.

I've used three Let's Resin silicone mold making kits of varying hardness scales and this is my favorite. It comes with large mixing cups marked with clear measuring lines and big tongue-depressor type wooden mixing sticks that do the job much better than the popsicle sticks provided with the smaller kits.I measured the amounts carefully, using two mixing cups and allowing a tiny bit more in the cup I'd be pouring from, to allow for the residual amount that would cling to the cup and not pour into the mix. Within a minute of starting the mix the silicone started thickening.I used a model made of (dried) air dry clay coated with a thin veneer of acrylic paint and a day later I had a perfect mold. I was nervous removing the model due to some stretching required but the cured silicone stretched easily with no damage and the model slid right out without a release agent being needed.This was the smoothest mold making experience I've had yet and produced the best result.As a bonus, it seemed to be easier to clean up than the other kits I've tried, wiping the inevitable sticky residue clean off my fingers with a paper towel, without the repeated scrubbing the earlier mixes needed. I love this stuff!

This silicone is very good quality mold making silicone. The 0A gets every little detail because it is a very soft silicone. Very easy to use it is a 1:1 by weight or volume. There are very small bubbles that comes out of this silicone when curing. This product is very well worth the price you pay.

I used this silicone to make 3D molds for my candle projects, and I was impressed with how flexible and easy it is to demold. The cured molds are soft, durable, and capture fine details very well.The only issue I experienced was with air bubbles. I mixed and poured the silicone carefully and tried different techniques to reduce bubbles, but I still couldn’t get completely bubble-free results. A few tiny bubbles remained, especially in detailed areas of the mold.Overall, it’s still a high-quality silicone and works very well for mold making. Just keep in mind that if you’re looking for a perfectly bubble-free finish, you may need additional equipment like a vacuum chamber or pressure pot. I would buy it again because the flexibility and overall quality are excellent.

Update*** my replacement for this item arrived Monday (it’s Wednesday) and I also received a second order that I purchased today. Both of them have expiration dates months past the first box and the boxes are a lighter shade of purple. Both orders arrived perfectly (it has been warmer temps tho) I used the replacement order yesterday and will use the new order tomorrow. Product is worth 5 stars. I think I may have just received some older product which made the original jugs more sensitive to the cold temps. Windchill alone was in the negatives.Giving 5 stars because I’ve used this exact product and know it works great. I always advise ordering 2-3x more than you feel you need. You will always need more. Product cures strong, tack free, and true to detail. Great value compared to local craft stores**Warning though be cautious ordering in the winter. It can freeze. Make sure you’re going to be home when it’s delivered as there anre not packaging measures to prevent it from happening. And if it does freeze the seams of the containers are a little weak. Expansion isn’t good. Causes containers to crack at the seam. Blending in. Leaving a hot gooey mess if you don’t catch it frozen. On the company’s part ordering an exchange is fast and hassle free. However both ups and staples consider it a hazard if you try to return it with all the liquid just laying in a bag in the box. I get it. The solidified parts that were solid just gooey could stay but the liquid part can’t. If you ever have this issue (hopefully you don’t) Save yourself the hassle and PROPERLY dispose of the uncured part before trying to return. Or else you get sent home after driving 40 mins one way and have to do it all a different day. Understandable just inconvenient. Replacement arrive with 2 day shipping in perfect condition.

The 0a silicon is very flexible and durable. It picks up object details well. Bubbles from the mixing process released without applying negative air pressure. That was surprising to me because even though I stirred carefully, it poured full of tiny bubbles.

I make a lot of Balloon Dogs and unfortunately the molds I had are wearing out. I went to buy more and the size I like are no longer available.I had some custom orders but this is a very complicated mold.I hate the split molds but that was all that was available.I got this in and it was advertised as 'Super Soft'.It is a bit pricy but it worked so well that my mind is racing to make other molds that my older Silicone could not handle.I anyone has used the dog molds before, you know that getting that head out through the neck is a pain. I actually trained about 313,00 artist how to use warm soapy water and where to massage it to save the mold.With the one here that I made. There is no issue. The head comes right out!I could not be more impressed and I have used a lot of brands in the past.

Love the ease of use for this product
