Glass microbeads are used to add weight to your soft plastic baits. Our glass beads are very fine, round, and have Excellent heat and moisture resistance. Because of they are round they adhere to the plastic better than salt. The more glass you add to soft plastic the stiffer and More opaque it will make it. So you will need to add softener to keep your soft plastic flexible. The bigger the um size the less opaque the soft plastic will be.
