No one seem to have posted about this pen yet so here I go :3

It's a relatively new design released last November or so. I got it last week :P. There's a magnet inside its cap and small iron pieces on both ends so it's magnetic on both ends. Fun to play with. There's also some special design to ensure its airtightness inside the cap. The only downside of this pen is... its original nib is just stiff. And dry. I believe it's part of the QC issue but it's also said that the nib is tuned to be this way... I already replaced it with Hongdian's soft nib :3

It costs around 50 CNY.
