I was never able to use my Japanese jumbo as originally intended as a safety due to leaking issues. The seal needs to be redone.... so I inserted two o-rings, one between the blind cap and the barrel and another between the section and the barrel. Now it is a capacious eyedropper filler with an osmiroid B10 nib.
