One of the most popular blank substrates would have to be the half-inch thick jade glass awards. We think they are popular because they are a happy medium between the costly optic crystal awards and the less impressive thinner awards, while being at an economical price point. This is important because awards retailers can achieve a greater profit margin; they don't have to spend as much to offer an item that has just as high perceived value. In other words, you get the most bang for your buck.
