Motorola Phone Saying "OK" Enamel Pin (90s)

We just love old phone-related merch, and this quirky pin is no exception. After all, what screams 90s more, than early cellphones? 
Why this specific phone has a face, or what it's agreeing to, we don't know, but we love it. 

Measures approximately 2,5 cm from top to bottom. 

Condition: Great!
