Teflon Whistle Tip V2.1 (510)
This unique 510 Tip allows users to swap sleeves as well as bore inserts for fully customised draw and style.
The included swappable airflow inserts are placed in the base from the top, and the sleeve slides over to hold in place. The insert bore diameters are 4.6mm (without insert), 4.5mm, 3.5mm, 2.5mm and 1.5mm.
The whistle style sleeve is made of PTFE (Teflon) for a smooth feel and prevents gunk build-up. The base is made of stainless steel, with o-rings to hold the sleeve in place, with knurling at the top of the base allowing for easy attachment and removal on devices.Features
