Thank you for showing me that link, but there are no boxes to buy.
I wrote here, maybe someone has it in storage and didn't put it in here.
I put the link so that:
1. you could see it in case you hadn’t found the catalogue entry,
2. others would see the box / set you’re looking for and maybe they would think
“eh, I’ve this box somewhere!”
Always easier with a picture
Does anyone have EMPTY box for set 6430 ?
It's hard to find here on Bricklink.
Best wishes
Of the 22 sets available right now on BrickLink, 1 had 2 copies that were New,
Sealed, 2 had it listed with the box, of those 1 had "missing inner trays",
the rest were Used listings. One used listing stated a black tap piece was missing.
Your chances of getting a box for this set are fairly low, unless you want to
get a spare set of parts for this box.
There were no box entries for sale at the time of creating this post.
I sincerely hope that helps you make an informed decision.
