I bought this at Walgreens and these are the wedges I use to apply foundation. These are good. The only thing I dislike about them is that it sops up foundation. To minimize this, I dot foundation on my face then I blend with the wedge. Then afterwards to prevent the buildup of bacteria and make-up on the wedge, I wash it with antibacterial soap. It washes well for re-use.
These are the most durable wedges I have used. One time I got away with four uses of one wedge! But usually I get three uses before replacing a wedge. And since it is firmer than most other wedges, it will soak up less foundation.
They're shaped like right triangles and I use the bottom of the wedge to apply my foundation. I use the thinnest part, the tip, to apply foundation around the corners of my nose. I make the wedge damp if I want a sheer, barely there look.
It is a very effective product and my make up goes on pretty well with these wedges. I think these are the cheapest wedges out there on the market right now. I would recommend this product to anyone, especially for the price.
