Made by Casio. Models are called Boulder and Rock. Cheesy names and very basic phones but I'm part of the minority that doesn't do much with a phone except talk. Strange I know.

They live up to billing. When I claim mine is waterproof it's based on actual immersion in my pool and having sweat rinsed off after sitting in a jersey pocket many times. Dropped a bunch of times too. I'm eligible for a new phone but I think I'll keep the $ in my pocket. Mine has "character."
