The 3 euro Preppy doesn't come in any kind of box. Based on look and feel, I would expect the pen to be somewhat more expensive (i.e. around 8 euros). It's a plastic pen and it will probably not live to see its first birthday, but it doesn't appear flimsy. I bought one with a 0.5 mm nib. Popped in the included Platinum blue cartridge and off I went. It's somewhat weird to see the ink flow across the section-enclosed fins of the feed. There are no fins outside of the section. The pen wrote straight away and puts a big, fat, confident line on paper. It's not a stub, so line width is more or less the same in downstrokes as well as sidestrokes. The nib is very, very smooth. On a scale of 1 to 10, scratchiness zero, tooth zero, feedback 2. It's like skiing over fresh snow. Very impressive, though purely as a matter of personal preference I'd like more feedback.
The 18 euro Plaisir comes in a cheapish plastic box with instructions and an included black cartridge. The instructions claim that the pen won't dry out for a year, even though it is a click-on cap. If that's true, then it's impressive. The barrel and the cap seem to be made of aluminium. Even though it's made of metal, somehow the design looks cheapish to me. Being 6 times as expensive as the Preppy, I'd say it looks only slightly more upmarket but definitely feels more upmarket. I bought one with a 0.3 mm nib, and after popping in the cartridge the pen wrote straight away. Being narrower, the nib offers more feedback than the 0.5 mm but is still incredibly smooth. On a scale of 1 to 10, scratchiness zero, tooth 1, feedback 4. Very impressive. I like this nib.
Both pens are nice to write with, in terms of ergonomics. I can use them unposted and the sections aren't slippery at all (even though I tested them on a hot summer day). I could easily do long sessions with these pens. I feel that both Platinums offer exceptional value for money, with the expected longevity of the Plaisir being the main reason for its higher price.
The fact that the nibs are easily exchangable between the Preppy and the Plaisir is a great bonus. Want another nib in your Plaisir? Buy a Preppy.
Both pens use Platinum's proprietary cartridge system. A converter is available (see photo). Also available is a small item that facilitates the use of standard international cartridges (see photo).
For fun, I compared them to my Pilot Metropolitan M. In terms of price, size and shape, the Plaisir and the Metro are very very similar, with the Plaisir being about 4 mm longer and 1 mm wider. A big difference is the feel of the section. The Plaisir has a very small step-down from barrel to section and no ridge at the low end of the section. The Metro does have such a ridge and a pronounced step-down. I like the Metro just fine, but the Plaisir is much easier to grip and feels more comfortable. In terms of writing, both are excellent pens. My Metro has a touch of baby's bottom; it's very subtle but it's there. It also offers slightly more refined feedback, of the pleasant kind, than the Plaisir. It's a tie, both pens writing very well, very smooth and very reliable. Heck, I've had issues getting 200-euro pens to write this good. Count me impressed.
