“The Kaweco Sport is a fairly small pen so this squeeze ink cartridge is also small. Therefore, as another reviewer noted, it's hard to get the ink in it more than halfway. I also found it a bit messy.
I note that Maddy M. suggests using a blunt syringe to fill it. I think that would work (and I might try it) but also, Milligram are now selling Kaweco Mini Piston Converters. I haven't tried them but the design seems to me like it would overcome the problems with the squeeze version.”
“I've never used a squeeze converter before but it didn't take me long to get the hang of using this. I'd highly recommend buying it at the same time as your pen, as this way you can experience all the fun of using bottled ink right away! To get the maximum fill capacity I'd suggest filling with a blunt syringe for those who may be more experienced.”
