4mm OD Ruby Pearls Balls Insert (10 Pack)

Works better than regular terp pearls and love the red look!

Nice product. Great price. Works great in my Puffco.

These work great for what I needed them for!

This set of ruby balls are on the spot! Quality is definitely there and there is a noticeable difference in performance. For one, it tasted cleaner. The heat retention is just a bit longer than quartz. I havent had any problems with discoloration at all. Great performance for such a good price! (Picture: Ruby balls are 4mm. The other balls are 6mm.)

these beads are like 1-2mm in size. if you got a 14mil banger, these will defenitely not work. maybe a mini rig..

These are made out of rubies. Just because their red doesnt mean their rubies. They make red glass balls too, but the rubies give a better taste and last a lot longer than other balls

A high quality lab grown ruby, well formed, nice surface, functions as promised.

Works well. No issues.

these rubies are more like, 2 or 3mm od. I am looking at a proper 4mm ruby right now, and it is huge by comparison
