This is a practical Sailor fountain pen maintenance kit which includes the following tools:
1) 1 unit - Multi-use 3ml syringe barrel (main unit)
2) 1 unit - a cleaning nozzle
2) 1 unit - Blunt syringe tip
3) 1 unit - Empty reusable cartridge to refill with any ink color of your choice.
The cleaning nozzle attachment can be used to flush out any remaining ink in the nib unit. Just screw the washing nozzle attachment onto the syringe barrel, draw up water into the syringe barrel, attach your fountain pen nit unit to the end of the nozzle, and flush out the remaining ink!
The ink syringe and blunt tip attachment can be used to suck up every last drop of ink from an ink bottle, as well as inject ink directly into most Sailor pen converters and empty cartridges. You can also use this unit to clean your Sailor converters and most of other types of converters as well.
I find that this is a very useful cleaning tool for most type of fountain pens.
