Tom's Studio Wren Single Spare Ink Reservoirs - Pack of 5

Spare cotton core reservoirs for the Wren pocket felt-tip pen. The cotton core soaks up fountain pen ink, storing it for use inside the Wren. They can be reused by rinsing out the reservoir until water runs clean through.

Optionally, you may fill the reservoirs with your favorite ink and save them in an airtight container to keep the ink from drying out.

Dimensions: 6x42mm for the Wren pocket fineliner pen.(pack of 5)
