A terp pearl, also known as a dab pearl or a terp ball, is a small spherical or bead-shaped accessory used in conjunction with dabbing, which is the process of vaporizing and inhaling concentrated cannabis extracts.
Terp pearls are typically made from heat-resistant materials such as quartz, ceramic, or glass. They are placed inside a dabbing nail or banger, which is heated to vaporize the concentrate. When the user inhales, the terp pearl spins and moves around, creating agitation and improving the vaporization process.
