This is the narrow, long spring that goes on the tip of the parker style refill. This spring is longer than the spring that came with the kit, but I have tested it on over a dozen kits and it works fine. Used with any kit that uses the parker style refill:

- Cigar
- Sierra (all styles of the Sierra pens)
- Flat Top
- Round Top
- Perfect Fit
- Cartridge
- El Grande
- Carbara

Price is for one spring
