With this adapter, you can use standard international cartridges in Platinum pens such as fountain pens, which greatly expands the ink cartridge selection available for the pens. One black standard international short ink cartridge is included.
Enables use of European size cartridges in Platinum Preppy, Prefounte, and Plaisir pens. I've used these for several months and they're fantastic!

I tried them in my Platinum Procyon, but they're too loose for that pen, won't hold the cartridge place. In my opinion, the Plaisir is the sweet spot for this product in terms of price/value. Very highly recommended. view less
