4mm OD Ruby Pearls Balls Insert (10 Pack)

Durable just get black easily and don’t turn back red

100% synthetic rubys. They turn to almost black when hot and back to that beautiful red when cooled and hit with a little swab of iso. I probably buy another set now I know theyre the real deal.

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.)

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

They leave a really gross after taste along with one exploding on me but hey, terps are terps. They are a very pretty color but doesn’t last long lol

Theyre little, round, red and they dont melt. All good.

Two day shipping turns into one week. Trash

Got the job done

really brings out the flavor
