Review on Plastic Disposable Specimen Pregnancy Ovulation by Peter Schwartz

I've used these to mix epoxy and they work great. First let me say that they are not durable. A cup is pretty thin. However, if you add two or three, they become strong enough to use. I actually like it better if you just pull off the lining and move on. The design is great and neater than any other mixing cups I've used. They are so effective that I can use one glove instead of two. Given that nitrile gloves are hard to come by and expensive, this is a huge benefit. The nose is so pronounced that it doesn't flow down the sides like most. I love the pen too. I can be sure that my bare hand will stay clean! There are wonderful mugs for epoxy. The only downside for me is that they are right handed. I usually sulked with my left hand so this was an adjustment. You can't beat the price in them. They are very cheap and very effective. It doesn't get much better! I'm very satisfied! If they were left handed and a little thicker they would be perfect!
