First popular in 2019. As glass artist looked for more efficient ways to distribute the heat amongst the dab, Terp Pearl’s were born. By having two or more pearls spinning around in your banger it allows the movement of your concentrate to be evenly distributed across the banger allowing for a nice consistent temperature in your dab. it’s important that you have a Fourtex or spinner cap that allows for the pearls to be spinning in your banger when using Terp Pearls!
