this is what i got http://www.hsconline.co.uk/blue-plastic-box-with-50xS1 the vials hold just over 30 grains (perfect for my pistol)
they also sell them loose as well as 7 gram screw lid ones http://www.hsconline.co.uk/shop/catalog/bottles i recommend the glass vials as the plastic ones soon discolour with the dust from the black powder and makes it imposable to see if any thing is in them (or left in them after loading)
7 grams = 108 grains
2 grams = 30 grains
2 grams =1.75 ml (in the vials i use)
the ones i got from the the above company came in a p50 mcm case gard ammo box for 44mag
