The HCigar Drip Tip Insulator is designed as a way to keep heat away from your lips. A great addition especially if you like metal drip tips since this mouthpiece will keep the heat away.
There are 2 styles of the HCigar Drip Tip Insulator:
Small: A very small insulator designed to be hidden between the tank and your regular drip tip
Large: Bigger version that has much more surface area, designed to dissipate much more heat
