These colourful one-hitters are made from borosilicate glass. These bright, portable one-hitters are traditionally used for cannabis consumption. They are 12mm in diameter, and feature a "restriction"; in other words, the glass is made narrow to slow the inhalation of ashes.
They are approximately 3.75 inches in length (each will vary slightly). They are strong, durable, and can easily be cleaned out with a pipe cleaner or a toothpick.
These can be made in any colour. Please message me for questions about this product and for an estimated timeline for custom orders.
