Cobalt Vial Bottles
These have standard caps not locking caps. Small sizes excellent for groups and conference.
5/8 dram = Dimensions(bottle): 1/2" width x 1" height
1 dram = Dimensions(bottle): 1/2" width x 1.75" height
If you wish a security lock cap then look at the 5 ml in the EuroCap bottles. The 5 ml is equal to 1.3 dram and also an excellent choice for conference or smaller amounts of oil.
