I'm looking to selling the Grand Piano 21323 (no box, instructions), Starry
night 21333 (no box or instructions), Super Mario 64 Box 71395 (no instructions
or box) and Nintendo Gaming set 71374 (no box, instructions).
I have split all sets into the bags they are in when you buy them, so they're
separated into labelled plastic bags. But I appreciate that without the original
boxes and 2 missing instruction manuals that they won't be worth as much.
Just looking for advice on where to sell them
If you wish to sell on BrickLink you have to apply to be a seller and have at
least one positive feedback (from buying on BrickLink). You could sell on other
platforms, such as eBay, Craig's List, FaceBook Market Place, GumTree etc.
etc.
