The icicle is an extendable and freezable tube for Randy’s Chill vaporizer. This piece is ideal because it stays colder for a longer period of time. This glass tube is made from handblown borosilicate glass and is 5.5” in length. Even when the tube isn’t frozen the extra length provides a cooler vapor than the regular tube. This glass piece is easily cleaned with 99% alcohol or any of Randy’s Cleaners.
