I purchased about 40 of these boxes for temporary storage from my local Kennards while I was rebuilding my cellar. They are usually $4.30 each when bought in bulk and come with bottle inserts, and hold 12 bottles laying flat. In good condition. Im based in Sydney inner west. If you'd like them, donate me a bottle or two of wine and you can have them. Will stick up on marketplace/gumtree soon if no takers but thought I would check here first. Approx 32 available now and another 8 or so will be ready in the next week after being unpacked. Happy to split if you want less. Must pickup.
