Features and Construction

Material and Build
The pens utilise an aqueous ink, which is a water-based gel ink. This type of ink is often formulated to offer a smoother writing feel and quicker drying times compared to some oil-based inks, and in this case, it is specifically noted for its reduced tendency to bleed on paper. The build of the pen includes the mentioned ink prevention mechanism, a technical aspect of the internal construction aimed at improving reliability.Size and Practical Fit
Each pen in the set is fitted with a 0.5mm nib. This fine tip size is a popular choice for detailed writing, note-taking, and drawing where precision is valued. The set contains 12 individual pens, which is a quantity that supports extended use before replacement is needed or allows for distribution across different bags, desks, or users.Uses and Placement
