Global Scale Modeller

Hi, I’m looking to buy separate sprues, especially from Hasegawa.

Does anyone know if/where I can do that?

I know you can mail Hasegawa about missing parts, but I have them, then I would be exploiting the system.
+ It can take anywhere from a week to several months to revive the parts, after writing to them.

Obviously eBay is one way of doing it, but I would like a reliable source of sprues.

Often a replacement sprue can work out almost as much if not more than buying a whole kit, to say nothing of the time you've got to wait. Some manufactures are much better than others. Interestingly and not the same circumstances, in that I had missing parts. A while back I contacted Fujimi over the missing parts, I used their website and their contact us. Stated what was missing and could they help, I thought I'd hear nothing to be honest. Within 2 weeks the part arrived from Japan and it cost me nothing

As you say you've not lost whatever parts you're after but, why not try the same see what happens, you've got little to lose Even if they charge you it may still work out cheaper than buying a whole kit.

I regularly find that I have made a mistake, snapped a part or sacrificed them to the carpet monster!
I have had to buy a second kit for replacement parts several times, expensive but better than missing out a key piece!
In future I will explore buying replacement sprues

Yes, found that Italeri does sprue replacements, and they do it for a small fee, for 12€ for the sprue I want. And about 20 days of shipping
