Updated following collection of some:
When replying please say how many you would like and also when you are able to collect.
The cd cases are all empty. The zips work. All of cases have some writing on, though this could be painted out with black paint, or covered with a label.
There are: six 29.5 x 17 x 6 cm cases each capable of holding 64 cds & one 16.5 x 15.5 x 7 cm case which will hold 48 cds
Alternatively the cases could be used for a different purpose if the cd holders were removed.
