I've got a NATS biro. Cheap and nasty corporate gift sort of thing- nothing you would treasure. Also had a NATS coffee mug that changed colour and the NATS swirly stripes appeared when you put hot coffee inside. Got sweet FA from the company when I retired though, not even a letter wishing me well. (Actually I think they were glad to get rid of me - bit of a thorn in management's side).
