Thicker and better is a little deceptive. The only part close to 5mm is the neck tube. The bottom chamber glass is definitely not 5mm. Hits good and looks good just wish the glass was thicker.

I already have the HVY 26mm clear bong and I love it. This is a tad larger and absolutely beautiful, the perfect daily driver. I haven't had it long enough to notice any permanent change but color does change due to viewing angle. It is beautiful and gives the hits I want, whenever I want.

A tad bigger than expected but it is a good piece for the price! The thin neck is what caught my eye. Simple piece definitely recommend!!
