4mm OD Ruby Pearls Balls Insert (10 Pack)

Really great product. I got the wrong size but that’s on me, will order from this company again if they have 6mm

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 go spinny spinny real good in my Peak. Two of them seem to work best. I use the Ball Cap and can get them to move around in there very well. They most definitely improve the volume and density of the cloud, and retain heat longer than bare ceramic. Super value also. I like having extras because they are small and I have already mistakenly picked one up still hot and dropped it, so eventually one might get lost. They bounce like crazy...

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.

Eh product. Pearls make little to no difference in wax distribution in a puffco. A part of me feels the pearls hinder the puffcos maximum output potential.

This isnt 4MM at all 2MM is closer to what id say it is. Still great synthetic rubies just not the right size

Product will get sucked down the tube you will be fishing pearls out of reclaim Good heat retention why 3 stars

Great product. Works great. Work as designed and arrived early

Great product. Works perfectly and correctly sized. Definitely recommended.

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.
