Koji Glass

Koji Glass is a rising name in the world of high-end American functional glass. It is best known for its handcrafted bong bowls and precision screen slides, which combine bold aesthetics with flawless function. Designed with the cannabis smoker in mind, Koji's work delivers the perfect balance of form and performance—you're curating your setup or replacing a bowl for your bong with something truly distinctive.

Every Koji piece is made by hand using durable borosilicate glass and features clean welds, vibrant colorwork, and thoughtful ergonomic design. From everyday function to collector-worthy additions, Koji Glass Bong Bowls are as reliable as they are visually striking.

Bong Bowls Designed for Real-World Use

Koji's signature style shines through in each bong bowl, often characterized by vivid color pulls, marble accents, and sculptural shapes that stand out without sacrificing usability. The brand offers both deep funnel bowls and screen slide options, ideal for cannabis smokers who want better airflow, cleaner sessions, and long-lasting durability.

Most Koji bong bowls come equipped with a 14mm male joint—the standard size for modern water pipes and rigs, ensuring universal compatibility across various setups. These slides are easy to grip, simple to clean, and built to elevate your bong's function and personality.
