The Wing Sung 3013 vacuum filling fountain pen is 100% copy of a TWSBI Vac 700. I won’t lie, I purchased the Wing Sung because the price of the Vac 700 is out of my reach right now  especially for a pen that I wasn’t sure I would like.

For $7.42, the 3013 is a steal. It feels well made when compared to some of my other knock off pens. The body is sturdy, threads well molded, and generally looks pretty nice. The cap continues the TWSBI knock off theme and looks startlingly similar to TWSBI’s caps. The clips is generic looking but sturdy. The finial is plain domed chrome. The cap is postable but throws the balance of the pen off.

The nib is the classic Wing Sung Pilot knock off, and mine is fine, and writes smoothly. The feed is clear plastic and also a Pilot copy. The grip section is round plastic and reminiscent of the TWSBI Diamond series.

The back end has a cap that unscrews. One must be careful to NOT unscrew the silver band just below the cap as that will allow you to removed the mechanism. Once the cap is unscrewed the piston slides in an out much like the plunger on a hypodermic needle.

The mechanism builds up a vacuum until the plunger reaches the bottom of the body of the pen, at which point the vacuum releases and sucks up ink. Getting a full fill takes some work and practice, but once done, this pen sucks up an enormous 2 ml of ink. To compare, most pens take up about 1 to 1.5 ml. A converter gets about .75ml, while a cartridge has around .5 to .75ml. 2ml is a huge amount of ink!

The only problem with it sucking up that huge amount of ink is that only only get to fill it once in a long while, and frankly, I really want to watch this thing suck up ink!

The nib is smooth and the grip is nice. I did fine that the body of the pen is a bit sharp, but this didn’t actually impact my use. The sharp area didn’t rest on my hand or under my fingers. I did use a sharp knife and patience to knock the sharp edge off the body of the pen. I know that the sharp edge was a complaint of some early Vac 700 users.

Overall, I really like this pen. At $7.50 it’s a steal. The combination of the fun filling mechanism, nice heft, and smooth nib makes this an everyday use kind of pen. That is to say, that since I received this pen and filled it I have not put it down. There is no getting around the fact that this pen is a direct rip off of the TWSBI Vac 700. After using this pen, I’m convinced I will like the Vac 700 and I’ll be using the Vac 700 as a carrot on a stick.
