This product is pretty good, if you can get it. Every color I've bought has a long piece of slime that has to be pulled out every time I use it. Even without shaking, there are massive bubbles that need to be popped or you'll have to do another layer.
Make sure you have all you will need for your project before you start it, because even If it is available, sometimes the cost is insane.
If I had it to do over, I would have gone with another brand.
