Wrappers custom made cases for Apple's numeric keyboard.
Waterproof Cordura outer is lined with cell foam and black microfibre with black elastic closures.
There is unlikely to be much on the market that fits this very long keyboard. It measures 47 x 13.5 x 3 cm.
We were asked to make cases by a company in the US that uses these keyboards out on location and finds they can be easily damaged with keys being dislodged.
