Size and Practical Fit
The pen body is about 140mm long. The pen tip is available in 0.38mm and 0.5mm. The 140mm body length is a stated measurement, and the two tip sizes give a choice between a finer and a slightly broader line.

The style options are 0.38mm and 0.5mm, and the quantity option is 10PCS.
Uses and Placement

The main use is listed as office and stationery. The pen is also described as suitable for student and examination contexts through the product title. Because the ink is non-erasable, it fits tasks where written marks should remain on the page rather than being rubbed out.
Event or Professional Use
For office and professional settings, the gel sign pen can be used for paperwork, forms, notes and signatures where a non-erasable gel line is required. The 0.38mm tip supports a finer line, while the 0.5mm tip gives a slightly broader stroke. The colour range includes black, blue, red, blue-black and black rod black, which can help separate categories of writing. The specification of 10 pcs/box supports keeping a box on hand for a desk or stationery cupboard.
Everyday Home Use
For students and general home stationery, the pen is suited to note-taking, revision and examination writing. The non-erasable refill means the writing is intended to stay on the paper. The 140mm pen body is a stated length, and the tip size can be chosen as 0.38mm or 0.5mm. Colour choices include black, blue, red, blue-black and black rod black.
