I might possibly have some Algot shelves to sell if you can be patient.
Moving house next week. Had some for ages but not sure at the mo if they’ll be needed at the new place...
Thanks bud, but think I've actually found the right ones now on ikea website. In black only you can get ones that have holes/vents in, so will just go with that.
Well done that man, cheers. Its ALGOT. Looks like they don't sell those holey shelves though anymore. Back to the drawing board!
