The 'Twister' is a patented, almost indestructible tension spring pure pipe, designed in Sweden. The hand pipe mainly consists of a stainless steel spring which can be bent in all directions. By bending the spring while inhaling, cool and fresh air is added as a booster. Specially designed heat-extracting fins chill the aluminium bowl swiftly. Find the air-resistance of your choice by twisting the stainless steel spring when attached to the bowl.
