This is a used Panasonic Toughpad FZ-N1, model FZ-N1CKLAAZJ, with 16GB storage and a 4.

Now, let's be upfront: this unit works fine, but it's not perfect.
The side cover is partially missing, and since it's used, you'll find scratches, scuffs, some tears in the rubber parts, dirt, and general wear from previous use.
Nothing that stops it from working, but it's got some battle scars – check the pics for details.

It's a tough little tablet built for job sites, field work, or industrial environments.
Panasonic makes these things bomb-proof, so even with the cosmetic flaws, it's still a reliable workhorse.

If you need a rugged tablet without payin' new price, this is a solid deal.
