Product information
[Type]: Disposable water-based syringe pen
[Specification] :0.05mm,0.1mm,0.2mm,0.3mm,0.5mm,0.8mm
[Scope of application]: Construction drawing design and drawing
Features:
1. Its light weight and easy to carry
2. No need to fill with ink, it is a disposable syringe pen
3. Feel good, ink flow is sufficient, generally can continuously draw a distance of 800 meters to 900 meters
4. The unit price is cheap, don't worry about the pen tip being damaged due to carelessness.
5. The pen is not easy to retract
Needle pens of three different thicknesses should be prepared in the design drawings, at least thin, medium and thick. Please note when using a needle pen:
(1) When drawing lines, the needle barrel should be kept perpendicular to the paper as much as possible to ensure that lines with uniform thickness are drawn.
(2) The drawing sequence of the needle tube pen should follow the principles of first up then down, first left then right, first curved then straight, first thin and then thick, and the speed and force of pen movement should be even and stable.
(3) When drawing with a thicker needle tube pen, there should be no pause in the writing and closing of the pen.
(4) In addition to being used as a straight line segment, the needle pen can also be connected with the compass and the compass to make a circumferential line or an arc line.
(5) Normally, the needle pen should be used and maintained correctly to ensure that the needle pen has a good working condition and a long service life. When the needle pen is not in use, it should be put on the cap at any time to avoid the ink at the tip of the needle drying, and the needle pen should be washed regularly to keep the pen smooth.
