Genuine 1980s black plastic tape/cassette drawers. Black, each holds 36 so total capacity 72 cassettes. Definitely not pristine - some chips and crack as per picture but they sit together nicely on a shelf and you don’t notice much from a couple metres away. I don’t want to bin them, too many memories! And I know how hard these are to find, I tried a couple years back.

Pickup Kelburn or postage at buyer’s cost (prob around $20 due to size) and risk.
