The rOtring Isograph Needle Pen is made of brass and can be cored in a standard way2 For painters who often use bottled ink, the ink filled ink bag is the ideal choice.3. The patented push-pull pen case is convenient to take the spiral ink core and clean it quickly4. The ink level is clear and visible5. The ink bottle is not included6. It can be used on various surfaces, such as line board, tracing paper or leather drawing paperSuggestion:When using, add ink, shake the pen head a few times, and click the pen tip on the paper a few times, then water will come out. Beginners suggest practicing with disposable needle pens first. This set of needle pens is a little difficult to handle. When drawing, the pen tip should be perpendicular to the paper as much as possible, because the pen tip is flat rather than conical. When pushing and pulling at an even and steady speed, the speed should not be too fast, and the pen tip is easy to bend. When the pen head is blocked, it can be carefully cleaned with clean water or special cleaning fluid. Or you can open the pen head and use the tip of a capillary needle to pass through it. Non professionals are not allowed to operate it.) In short, this pen is more delicate. Please cherish it and use it correctly to make it last longer. buy lanjingyi 1pc rOtring Isograph Needle Pen 0.1-0.8mm Repeated replacement nib Addable Ink hook line pen Hand-painted/ Drawing Pen rOtring 0.18 without regret! buy lanjingyi 1pc rOtring Isograph Needle Pen 0.1-0.8mm Repeated replacement nib Addable Ink hook line pen Hand-painted/ Drawing Pen rOtring 0.3 without regret! buy lanjingyi 1pc rOtring Isograph Needle Pen 0.1-0.8mm Repeated replacement nib Addable Ink hook line pen Hand-painted/ Drawing Pen rOtring 0.35 without regret! buy lanjingyi 1pc rOtring Isograph Needle Pen 0.1-0.8mm Repeated replacement nib Addable Ink hook line pen Hand-painted/ Drawing Pen rOtring 0.6 without regret! buy lanjingyi 1pc rOtring Isograph Needle Pen 0.1-0.8mm Repeated replacement nib Addable Ink hook line pen Hand-painted/ Drawing Pen rOtring 0.13 without regret! buy lanjingyi 1pc rOtring Isograph Needle Pen 0.1-0.8mm Repeated replacement nib Addable Ink hook line pen Hand-painted/ Drawing Pen rOtring 0.1 without reg Ink Filling Type:Repeated Filling ;Package Quantity:SINGLE; Dual-side Writing:No Use:Promotional Pen; ; ; ;
