Pentel's mission is to develop pens offering a satisfying writing experience & value for money, this plastic fountain pen does seem to have both.
From flexible to firm depending on how you hold the pen & the amount of pressure used, the delta shaped double sided nib on the Pentel Stylo Plastic Fountain Pen will produce variable line widths.
This pen has a white barrel with brightly coloured logo's & branding, they are available with red, black or blue water based ink & each has a colour coded end cap & tip housing.
The Stylo JM11 nib is not fussed which angle you hold it at delivering a flexible response on one side whilst the other is more rigid.
This Pentel's nib will wear to the style of the writer over time & thereby offers a unique writing experience.
