Have any left handers experienced smudging when writing with this pen?

I’m a hook writing lefty. Absolutely no smearing with these pens.

I see some people are saying that these pens are actually fake, is that true? or the quality is substantially lower than the ones sold in Japan?

I love these pens! Although the gel ink is not as dark as the refills I purchase from Jetpens.com, it still has the same smooth writing quality. However, if you are particular about the ink and prefer the vibrant black ink like the Japanese pens, then I recommend you go to Jetpens.com. Just keep in mind that the pens are sold individually and quite pricey. The ink refill alone is between $2.50 to $3.50 depending on the color. The.4mm is the perfect point for me, finer than a .5mm but not as thin as a .3mm. Hope this helps a fellow pen fetish-er like me!
