This item is brand new but been in storage for a while so i cannot confirm the exact model this is for, but this seems to be for a macbook air early 2015 from the comparisons i took with other devices. Will be more than happy to provide additional photos for any series buyers. 

Condition is brand new and never been used, comes as a 3 piece set for the bottom, top and track pad. Micro fibre cloth and original dbrand shipping envelope will be included.

any questions please feel free to ask.
