These Pulsar Bicolor Glass Terp Pills feature a pill shaped design in various bright colors. These 15.75mm to 18mm terp pearls have a thickness of about 6mm and are made to improve the vaporization of concentrates. To use, simply drop 1 or 2 terp pearls into a banger before heating it up. As you heat the banger and your concentrates, the beads will heat too and can be rolled to maximize each draw.
