If you are familiar with Mushkin products, then you wouldn't be surprised that the memory modules are protected by their trademark Air Boxes. The Air Box takes up a whole lot of space, but is capable of protecting the modules from even the harshest 'punishment' from courier services!
The Air Box is actually a dual-chamber bag with a pouch in the middle. The pouch is where the memory modules are placed. When inflated, the Air Box forms a protective air barrier around the memory modules.
This protects the memory modules against static as well physical damage during delivery. In fact, since the contents of the Air Box's pouch are hermetically sealed after inflation, the memory modules are virtually impervious to damage by rain, seawater and other environmental hazards!
Here is a picture from Mushkin's website that demonstrates the durability of the Air Box. Take a look at how tough it is!
