Most Mac Book Air owners use a cover/skin to protect their computer. Maclocks created a simple but clever solution: it incorporates a neat cover that also protects your Mac Book Air via an integrated built-in security slot that can accommodate any of the standard cable locks sold on the market. Once the case & cable are locked together, thieves can't detach the case without damaging the Mac Book Air. This makes the Mac Book Air Lock flexible & light, not to mention stylish, so you can easily pack it in your bag & take it with you wherever you go.
