It seems there is no review of this new Chinese pen so I try my best.
Wing Sung 6359 is one of the new pens produced by the revived Wing Sung company - its production started in 2017. It is yet another Lamy-inspired Chinese pen and the inspiration by Lamy AL-star was fairly exhaustive in this case. The major reason why I decided to try it is the nib which seems very similar to Lamy nibs. Spoiler: they are interchangeable.
Appearance and Design
The design is far from original, it is essentially a Lamy AL-star. The differences are minor. Probably the most visible one is the clear transparent section (section of AL-star is smoked) which is cool.
The pen is available in several colours. I chose the one named coffee which is a bit tricky because it depends on the light. It is based on dark brown which leans towards purple, especially under an artificial light. So the pen colour looks a bit different in various environments.
Construction and Quality
Very satisfying, The manufacturing is close to perfect, everything fits, surfaces are smooth, no wiggling, no burrs.
I do not own the AL-star, so let's compare the pen against Lamy Safari. As you can see, it is very close:
Of course, some differences exist:
My only construction-related complaint is the screw of the barrel. It is fairly course and made from different materials - the section ends by a plastic screw and the barrel contains a metallic one. I would expect some wearing here. You have to be careful when you mount the barrel.
Weight and Dimensions
The pen is a light one. Complete pen weights 22 g, removing cap decreases the weight to 10 g.
Closed: 139 mm
Uncapped: 129 mm
The pen can be posted but I can not see a reason to do it. It is long enough and by posting it becomes a very long top-heavy monster.
Nib and Performance
As I said, the nib is almost identical to standard Lamy Z50 nib. Its shape is a bit different but the fitting is compatible, so Lamy nibs can be used on Wing Sung 6359. This is a great thing because the pen is available solely with the extra fine nib.
Hairline lovers will be disappointed - the nib seems to be subtle but it writes wider line than Lamy EF. For the comparison, I tried all four combinations of 6359 and Safari pens and nibs. Plus JoWo EF has been added. As you can see, the Wing Sung EF is visibly wider than the other two EF nibs:
Wing Sung nib outperforms Lamy significantly in all other disciplines. It is very smooth (Lamy has some feedback) and a bit springy. It definitely can not be called soft or even flex nib, but there is some give. Lamy is a nail.
I am not an ultra fine line aficionado. A smooth and springy nib is much more important for me than a needle. Wing Sung nib fits my preferences perfectly. Writing with it is a pleasant experience. Of course, it has the triangular section which may be repulsive for some of you.
I experienced some unsteadiness in the ink flow but splashing the pen seems to fix this. Now it writes like a dream. No skips, hard starts or other problems.
Filling System and Maintenance
It is a converter-filled pen, the converter is included. Even the converter is seriously inspired by Lamy:
Cost and Value
I purchased the pen on eBay for some 4 USD which is a steal. This pen is very hard to beat it the price/performance ratio.
It is a great pen. It looks good, its manufacturing quality is very good and it writes like a dream. If the triangular section is not a problem for you I can highly recommend it.
