If the buyer arranges a courier, I would package it up the best I could for a small fee as it would take a lot of bubble wrap. Sadly I wouldn't be able to flatten it as the corex tray won't fold.

Very good condition, an easy solution to wanting a smaller hauler or a carry-all holdall. Very rare in the UK, this one came from America.
Collection only due to size from Kendal, South Lakes.
