New pen day, Lanbitou 3088a, which is a revision of its 3088 model (which is a copy of Platinum's Curidas). It is a bit larger than 3088, with more intimate changes that made it bit more distinct from Curidas.

Sadly, it's mechanism is not good enough and the nib dries out relatively fast (<10minutes). The same issue also exists in the smaller 3088 model.
