4mm OD Ruby Pearls Balls Insert (10 Pack)

Really good for the price Also they stay warm long so the dab gets a nice temp

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

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

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

Manufactured Rubies, perfectly free of flaws and mine received were all a perfect color match. Perfectly round, polished, no hole. I believe they’re made for higher temperature vape pipe valves but my use is for a long wearing jeweled movements in mechanical pivot arms. Am very pleased with the product I received. Would make nice jewelry items too. Long term wear TBD. Wish I could find them in 2-3 mm too..

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

Got the job done

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

Perfectly sized for any “e” item; peak, carta, oura

Works great but they are a little too small for my set up
