It recognized me, (my computer, and I'm a frequent flyer Amazon), and I would be concerned that your link works properly so you get your due. I don't have a handle on HTML and I feel as though I don't know the lingo.Д«ottom line, when I click your link to look at the blunt needle and syringe I went to Amazon, but what loaded was only slightly comprehensive. It also occurs to me that it may have something to do with different formatting from one country to another or one operating system to another.

I think your affiliate link(s) may be busted. I have been an Amazon affiliate for a minute about 5 years ago. I have only begun to explore your site and I find value everywhere I look.Д«ut, I did find a glitch and wanted to let you know. From the looks of things, I have a feeling you are sharing your knowledge and expertise internationally. Thank you for your service(s) to the greater community.

Regular maintenance should see these pens last for years. If the ink dries in the small pen tip, it is going to clog and be very difficult to unclog. The thinner the line, the more maintenance is required. If you need more variety then 0.1 and 1.0. If you're buying individually, I suggest getting a few line weights, the more popular ones being 0.3, 0.5 and 0.7. You can buy the pens individually or in sets. If you're looking for a refillable technical pen, I would recommend the Isograph over Rapidograph. Overall, the Isograph is easier to maintain and refill. The Isograph ink cartridge has a larger opening and you can easily squeeze ink into it with the Rotring ink bottle. It's more economical to refill with your own ink than having to buy disposable ink cartridges. Hence the better way to refill the Rapidograph is with a blunt needle and syringe. If the ink cartridge opening is blocked, no air can come out and no ink can go in. If you refill the Rapidograph's ink cartridge by inserting the Rotring ink bottle's funnel, the ink is going to block the opening. Rapidograph is meant to be used with disposable ink cartridges while the Isograph has a cartridge that can be easily refilled. But be careful not screw it so tight that you can't remove it later. It's likely to get stuck because of ink or dried ink. If you have problem removing the Rapidograph air channel, you can screw it to the back of the pen's body and pull it out gently. So cleaning the Rapidograph may take longer time. With the Rapidograph, I was not able to dismantle the air channel (the one fused to the tip) to remove the pin that's inside. The Isograph can be dismantled completely and easily. Performance of both Rapidograph and Isograph are the same. I'm not sure if the Rapidographs from Koh-I-Noor are similar to Rotring's though. Rotring is not the only company that makes the Rapidograph pen, the other is Koh-I-Noor. The green pen at the bottom is the Rapidograph. Both are available with line widths from 0.1 to 1.0. Both are technical pens that create strokes with uniform width. They are both plastic body pens with the exception of the metal clip and pen tip. The main difference between the Rotring Isograph and Rapidograph comes down to the refilling mechanism.Д«ody design of the two pens are quite similar.
