Whats a terp pearl we hear you say?  Its a magical little ball that stirs your concentrate in your banger.  Available in both 6mm & 8mm, this little fella does all the hard work for you stirring your dab so you can just sit back and enjoy.  It works with a directional carb cap by directling the airflow against the ball, forcing it to spin at the bottom of your banger.  We love them and we know you will too.
