The Restrictor Discs are a game-changer for the Sticky Brick lineup! These 316 Stainless Steel discs sit between your flame and your herb in your Brick. They put your Sticky Brick on "Easy Mode", enabling you to learn the proper technique while greatly reducing the possibility of scorching your herb. They serve to reduce the direct heat that can come into contact with your flower to scorch it, and allow you to hold your flame much closer to your intake, or even to use a larger flame. If you've ever struggled trying to use a Sticky Brick, or want to experiment with a larger torch, or just want a more straightforward experience, I highly recommend these!
