12.5" Gradient Style 7 mm Glass Bong with 4-Slit Downstem

12.5" Gradient Style 7 mm Glass Bong with 4-Slit Downstem

The 12.5" Gradient Style 7 mm Glass Bong is a medium-size borosilicate glass water pipe with assorted gradient designs, a 5" base and a 2" tube diameter. Built with 7 mm thick glass, this piece is made for customers who want a stronger-feeling everyday bong with more visual colour than a plain clear tube.

This 12.5-inch gradient glass bong includes a thick bowl for a 14 mm joint and a 6" downstem with 4 slits, giving it a practical setup for dry herb or legal smoking material where permitted. The assorted gradient finish helps separate this bong from similar 12" to 13" glass water pipes by giving each piece a bolder display-ready look.

Main Feature: Assorted Gradient Style Design

The strongest differentiator is the assorted gradient design. Instead of a basic single-colour or clear glass look, this bong uses a gradient-style finish that adds more colour, depth and personality to the piece. Designs are assorted, so the exact colour pattern may vary.

7 mm Thick Borosilicate Glass

Made from quality borosilicate glass with a listed 7 mm thickness, this bong offers a more solid feel than many thinner everyday water pipes. Borosilicate glass is popular for bongs because it handles heat well and is easier to clean than many non-glass materials when maintained regularly.

12.5" Medium Bong Size

At 12.5" tall, this piece fits the medium bong category. It gives customers more chamber size and tabletop presence than a mini bong while staying easier to store and handle than taller 16" to 20" glass water pipes.

5" Base and 2" Tube Diameter

The 5" base gives this glass bong a stable footprint for regular tabletop use, while the 2" tube diameter gives it a wider tube profile than many slim compact bongs. This makes it a strong choice for shoppers who want a medium water pipe with a more substantial feel.

4-Slit Downstem Included

This bong includes a 6" downstem with 4 slits. The slitted downstem helps diffuse smoke through water before it travels up the tube, giving customers a simple filtration setup without relying on a built-in percolator chamber.

Who Is This For?

The 12.5" Gradient Style Glass Bong is best for adult customers who want a medium-size glass bong with 7 mm thickness, assorted colour styling and a slitted downstem setup.

It is also a strong option for shoppers who want something more unique than a plain clear bong but do not need an oversized glass piece or complex multi-perc design.
