All FlexOffice caps comply with international safety standards attempting to mimimise the risk when children accidentally inhale the pens caps; as a result vented caps have a hole to comply with these regulations.

The safety of children is considered as FlexOffice’s top priority. Our Colokit products correspond to ASTM D-4236, EN 71/3 standards (all of the potentially hazardous components of the art products are clearly labelled on the product packaging).

It is not necessary to store a FlexOffice pen with its point facing down. However, we do recommend protecting the point when the pen is not being used. In the case of retractable pens, the point should be retracted when not in use, and pens with caps should also be protected after each use.

Carefully pump and rock the nib on paper to release the liquid chalk until liquid has covered the nib. Do this at right angles to surface. Continue until the pen writes a satisfactory line. Re-saturate the nib as necessary by repeatedly depressing the nib onto the upturned cap of the pen.


12-pcs/box, 600 pcs/carton. Packaging can also be modified as per customers’ requests as long as they meet the MOQ requirements for each item.


Line Width refers to the actual “line mark” made by a writing instrument on a substrate (usually paper). Normally, this is designated by the labeling of: 1mm line, 0.35mm line etc. The actual line width may vary based on (a) the writing pressure, (b) the absorbency or type of paper, and (c) the speed with which one writes. 

Ball Diameter refers to the “spherical ball part” of the writing instrument’s nib. Labeling on packaging will refer to this like 0.5 mm ball ø ( the “ø" symbol means “diameter”). The ball diameter indication is only used for writing instruments utilizing “ball nib technology” and not used for those utilizing “fiber or plastic nib technology." 

So one term refers to the “end result” of making a mark on paper (line width) and the other term refers to a “part” of the writing instrument (ball diameter).

Regular crayons which has main ingredient in its formulation is paraffin wax mixing with pigment colorant and some additives. The plastic crayon has a special  formulation as a compound of paraffin wax and plastic resin. Therefore, plastic crayon is harder than regular crayon. Moreover, it’s erasable and not adhere to the skin and hands while using.

Oil pastels are softer than crayon and are a recommended choice for light, fast, permanent colours.
