Bags of Ruby balls, available in 3mm or 4mm, for use with a wide range of heater housings and cooling units! Being made from ruby these can be also be used as terp balls. Ruby balls heat faster and retain more heat than the Borosilicate balls, providing a more consistent vapour experience when used inside a housing. Both options are great for vapor cooling though ruby does have the edge here too.
Also available are 4mm or 5mm "Clear Ruby" balls
Want to switch your ball size over but don't know how many you need? You can now just ask Google! Example - "if 200 x 3mm balls fit in a space, how many 2mm balls would fit?"
Includes

(Yes the 6mm ones are expensive, no the price is not a typo, a 6mm sphere has 3.375 times the mass of a 4mm sphere and they're less common so are produced in smaller quantities)
