These 3mm Ruby (Lab Created) gems have a number of different purposes but mainly used for  heat sink vaporizer tech in this case.  Pouch is filled with ~250 gem cut 3mm ruby or 6g. The following are estimates of how many bags it will take to fill up some of the diffusers we sell: B0- Just a tad more than one bag.  You could probably get away with one bag if you want.  You could top it off with a few larger 3 or 4mm ruby balls or just leave a little open space below the screen and use one bag only.   B1 (injector or 22mm diffuser)- You'll need two bags to fill it all the way.  One gets you most of the way there but there is too much space at the top.   B2 (injector or 22mm diffuser)-  You'll need two bags to fill it all the way.  One gets you most of the way there but there is too much space at the top.   Mercury Diffuser- You'll need three bags to fill it all the way.  Two gets you most of the way there but there is too much space at the top.  This is with the mesh screen, the machined screen is a bit thicker but It will still take three bags to fill it all the way.  You'll have some left over for other applications.   Venus Diffuser- You'll need three bags to fill it all the way.  Two gets you most of the way there but there is too much space at the top.  This is with the mesh screen, the machined screen is a bit thicker but It will still take three bags to fill it all the way.  You'll have some left over for other applications.   TKO Diffuser- You'll need three bags to fill it all the way.  Two gets you most of the way there but there is too much space at the top.  You'll have some left over for other applications.   VGoodiEZ takes no responsibility for personal injury or damage to personal vaporizing equipment as a result of modifications with these beads.  Hot balls are dangerous too so be careful!  Email sales@vgoodiez.com for larger quantity price.
