Finding the correct cartridge or converter for your fountain pen can be a little tricky. Usually, there is no item number or branding on the part you need to replace. Let Goldspot help you find the compatible refills for your pen. For over 20 years, we've fueled writers with fresh ink and refills for their fine writing instruments.

Most modern fountain pens use a cartridge/converter filling system (c/c for short) giving the writer the option of using a pre-filled, disposable ink cartridge or a piston-operated converter to fill with bottled ink.

"Standard International" cartridges and converters are commonly used in most fountain pens. International cartridges are made in short or long sizes. International converters are made in one size. A variety of manufacturers produce the same style of cartridge or converter and they are all compatible with each other.

On the other hand, certain fountain pen brands may use cartridges and converters that are proprietary (made to fit) their pens. Within a brand, there may be a few different types of cartridges and converters that fit particular pen models.

Use this chart below to find the brand of pen you use and see if it is compatible with standard international cartridges/converters, or if it uses proprietary cartridges/converters.
