Now , the converter is working very well. Review: Very good! - The reviewers that say this converter cannot be fully filled are wrong. You should patiently full it up and remove the air while the pen is upside down then fill it up and you should have a full fill. Good ink flow, feels a bit cheap for the price I paid. I like the design. ## Features - converter - pilot converter - Good Pen ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B019W0PO68 | | Best Sellers Rank | #2,195 in Office Products ( See Top 100 in Office Products ) #45 in Fountain Pens | | Brand | Pilot | | Brand Name | Pilot | | Country of Origin | Japan | | Customer Reviews | 4.4 out of 5 stars 2,972 Reviews | | Global Trade Identification Number | 00072838698100, 04902505515330 | | Importer Contact Information | PPIN PRIVATE LIMITED | | Ink Colour | Black | | Item Dimensions | 7.1 x 0.8 x 0.8 Centimeters | | Item Type | Stick Ballpoint Pens | | Item Weight | 6 g | | Item dimensions L x W x H | 7.1 x 0.8 x 0.8 Centimeters | | Manufacturer | PPIN PRIVATE LTD , PLOT NO 255, SECTOR 6 , IMT MANESAR , GURUGRAM HARYANA 122052, Pilot Japan | | Manufacturer Contact Information | PPIN PRIVATE LTD , PLOT NO 255, SECTOR 6 , IMT MANESAR , GURUGRAM HARYANA 122052 | | Manufacturer Part Number | CON-40 | | Model number | CON-40 | | Number of Pieces | 1 | | Packer Contact Information | PPIN PRIVATE LTD , PLOT NO 255, SECTOR 6 , IMT MANESAR , GURUGRAM HARYANA 122052 | | Point Type | Fine | | Style | Fountain | | Style Name | Fountain | | UPC | 072838698100 | | Unit Count | 1 Count | | Warranty Description | 1 YR WARRANTY | ## Product Details - **Brand:** Pilot - **Item Weight:** 0.01 Pounds - **Item dimensions L x W x H:** 7.1 x 0.8 x 0.8 Centimeters - **Number of Pieces:** 1 - **Style:** Fountain ## Images ![Converter CON-40 (Fountain PENS) - Image 1](https://m.media-amazon.com/images/I/714+wm9oclL.jpg) ![Converter CON-40 (Fountain PENS) - Image 2](https://m.media-amazon.com/images/I/51HSkp6PmvL.jpg) ## Questions & Answers **Q: Would someone please explain how this works? i understand a converter is used so i can use other bottled inks. how do i use it?** A: Put the converter inside the pen (just like a cartridge), put your pen's nib inside the bottled ink, and then screw the converter's screw mechanism at the back, It'll vacuum the ink into the converter just like a syringe. Tip: for a better fill, screw and unscrew a couple of times so no air is left while filling. **Q: Will it fit in a pilot Kakuno?** A: Yes. The con-50 and con-70 also fit. The con-40 replaces the older con-50 **Q: Will this fit pilot mr animal collection?** A: This converter fits all modern Pilot pens, except a few sold in parts of Europe which are altered to take International style cartridges. I'm not sure if those can take a Pilot converter. **Q: Does it work with any pilot fountain pen?** A: No, this does not work with all Pilot fountain pens. I'm not sure how familiar you are with fountain pens, but some fountain pens, like the Pilot Custom 823 have built in ink receptacles that are vacuum or piston fillable. So you couldn't use this converter with those. But you can use this converter in any Pilot pen that uses ink cartridges. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice sturdy tranparent converter *by A***K on 22 November 2025* Initially, ink sucked by converter was very less.
