Query: Best Concealer

I have used this product for years. Because it has become so obscure, I have tried other concealers and have not been happy with them. This product covers well and doesn't become clotted in the eyelids. The color that I use is perfect for me as well, which I have found hard to match by other manufacturers.I wish they would bring this product back to stores so it was more obtainable.Unfortunately, because of the current cost, I will have to keep trying to find another product. Not happy about it!
