Sheaffer refills are all quite specific to the pen, so you need to be a bit more aware of which one you require when making a choice. Some of them will only fit certain models.
We recommend trying to match your existing refill to the photo and checking the product description for guidelines on which pens they will fit.
Should you need further expert guidance then please feel free to contact us.
Any pen refills on this page not made by Sheaffer will still be compatible with their pens, see the product descriptions for more information on this.
