So I've been looking for a new pen and I've layed my eyes on this model and now I want it. The problem is that I can't find it in European stores. I know it's a limited edition but recently I found it on jetpens, they did an edition for North America. On jetpens the pen costs 30 but with shipping and taxes it gets to 50€ so not really convenient.
Is there a cheaper way of ordering this pen? Could I order from an Asian shop?
Yes. Although I have not seen any other models with a red painted/powdercoated clip, either. Usually they're chromed.
You can push out the plug in the end of the cap with a suitable poking object. It has a flange on the inside end that plugs in to the rubber sealing doohickey inside the cap. Once that's done you can slide the clip out. You have to rotate it to get the prongs through. Installation is the reverse of disassembly, although if I were you I'd put a drop of silicone on the end of the rubber seal to help get it back over the flange in the plug.
