4mm OD Ruby Pearls Balls Insert (10 Pack)

They look and function well, Im not sure why people say they turn black, they darken up, but they return to color.... Update, still working great, still the same color.

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.)

Overall product works AMAZINGLY! However, it was supposed to be a 10pk and i only got 7 of the 10 terp balls that I was expecting. Either way though I was short a couple still very much worth the $10 that I spent on them and my fiancé LOVES them.

Why do they turn black? At first they would turn black and back to the original color once it cooled down and dabbed out of but now they just stay black-_-

Do it....

I recommend getting 6 mm for 25mm banger

Got the job done

Too expensive

Not what i expected

do what theyre meant to do, I have yet to have issues.
