13" Calavera Hydrographic 7 mm Glass Bong

13" Calavera Hydrographic 7 mm Glass Bong

The 13" Calavera Hydrographic 7 mm Glass Bong is a medium-size glass water pipe with bold Calavera-inspired hydrographic artwork and a stronger 7 mm glass build. Designed for customers who want a more decorative bong than a plain clear tube, this piece combines everyday function with a skull-style artistic finish.

This 13-inch hydrographic glass bong includes a thick bowl for a 14 mm female joint, a 5.5" stem for an 18 mm female joint and a 3-piece setup. The assorted Calavera designs make each piece visually distinct, making it a strong option for shoppers browsing themed bongs, skull bongs, thick glass bongs and unique water pipes in Canada.

Main Feature: Calavera Hydrographic Artwork

The strongest feature is the Calavera-style hydrographic design. The skull-inspired artwork gives this bong a more collectible, display-friendly look than a standard single-colour glass water pipe. Designs are assorted, so the exact artwork may vary.

7 mm Thick Glass Construction

The listed 7 mm thickness gives this piece a more solid feel than many thinner everyday bongs. It should still be handled carefully, but the thicker construction makes it appealing for customers who want a medium glass bong with a stronger build.

13" Medium Bong Size

At 13" tall, this bong fits the medium bong category. It gives customers more presence than mini bongs while staying easier to store and handle than larger 16" to 20" water pipes.

18 mm Downstem with 14 mm Bowl Setup

This bong includes a 5.5" stem for an 18 mm female joint and a thick bowl for a 14 mm female joint. The 3-piece setup gives customers the main parts needed for dry herb or legal smoking material where permitted.

Who Is This For?

The 13" Calavera Hydrographic Glass Bong is best for adult customers who want a medium-size 7 mm glass bong with bold skull-inspired artwork.
