These are designed for a 13" and 15" laptops. I have the Space Your Face on my 15" macbook and the GD-Summer is the 13". The 15" could easily be cut down for 13" laptops too.
In original, unopened packaging.
"Made of premium, patented 3M vinyl. Defends your device from scratches, allows for easy application and removes cleanly without leaving residue."
Let me know via PM if you are interested. $12 including US shipping.
I'll be posting a Mutron Micro V and some JBL K120 pairs soon too...so let me know if interested (just not prepped with photos yet).
