What pens use a 1.5mL vial? I see the vials and just wondering what pen they are used with. Or is it simply just a thinner vial and if you select 20 units it would deliver 10.
They're slightly shorter and thinner. They wont fit in any of the pens we have. The pens that use them are harder to find and disposable.
