I offer that as partial explanation, however, as to how I came to be the owner of a pink pen called a "Cartelo 100":
It was on eBay for $0.99 USD with free shipping; how could I resist, when I was looking for lambs to sacrifice upon the altar of inky inquiry?
The descriptions - and photos - in the listing on eBay were pretty un-helpful; when I bought the pen, the photos actually weren't even loading, so I didn't have the greatest idea what I was getting.
What I got is a heck of a nice pen - possibly one of the nicest pens I've ever used. And don't worry, it comes in colors other than pink.
Let's go through the basics here:
Length capped: 135mm
Length posted: 145mm
Nib: fine stainless steel hooded, with tipping
Filling mechanism: quite nice removable piston converter with glass or plastic bb inside
Body: enamel or lacquer over brass
Cap: matte aluminum(?) with un-sprung clip
It's a pretty average sized pen - similar to a Parker 21, or a Lamy Safari, and so on. The metal construction gives it a nice heft - it's not featherweight, but it's not "heavy", either; it has a nice quality feel to it, and the fit and finish are fantastic. The cap is snap-fit, and does so firmly and securely. It comes in a kind of useless cardboard presentation box that does a good job protecting it in the post. The cap band and converter are marked "Car Telo" in English, along with a picture of an... alligator? Crocodile?
The nib is a fine hooded affair of stainless steel, lays down a perfect moderately-wet line, and is pretty much perfectly smooth. This is a pen that I could write with for hours with at a time... and have.
This is, like I said, one of the best nibs I've come across, and from a manufacturer (or at least brand) that seems virtually unheard of. I am almost unreserved in my praise for this pen; I am so very close to suggesting that if you like medium-sized pens with hooded nibs, you owe it to yourself to bid on one of these babies in the color of your choice.
There's this one little thing...
A thing the seller is kind of hoping you'll overlook, I think.
A thing which will either make this pen a "must have" for you...
...or completely break the deal and ensure you'll never buy one of these pens.
Someone, somewhere, did a really good job of trying to make this pen cute, in the way that only Southeast Asians can manage.
You see, the humble Cartelo 100 has personality - and a pair of fake rhinestones (Boring old BCHR fans might want to look away now):
I'm still undecided on whether that's an appalling travesty to pendom, or the most awesome bit of cuteness ever to sport a nib. I mean... I mean... I have a very nice Sheaffer Snorkel, and a Pelikan, and several Rotrings, and a military-clip Tuckaway, and a nice Ero piston-filler, and a red Esterbrook dollar pen with a 9-series flex nib; I'm a Serious Fountain Pen Afficionado, right? But the horrible truth is I now have a (pink!) pen with a pair of rhinestones on it and a crazy lizard's mouth design thing going on at the business end. Rhinestones! Pocket bling! Cuteness! Whatever will I do?
Suck it up and buy one in blue, or maybe black. Or both. They're that good of pens. Function over form, baby. Function over form.
Cartelo 100 pens can be had on eBay in a bewildering variety of colors. That's where I got one, and where you might want to think about doing the same...
