Mid-2012 Macbook Air. You would also receive a charger and a (unused) clear silicone keyboard cover.

Specs:

1.8 GHz Core i5
Model: A1466 (EMC 2559)
RAM: 4 GB
Storage: 128 GB SSD

In good condition, given that it is 6 years old. Selling because I needed more storage space.

Let me know if you're interested, or if you'd like any additional information!
