Query: Great anti-static mat

Need an anti-static mat for under a PC case which is oriented in the VERTICAL position? This should do the job nicely. I'm very pleased. The picture shows to include an anti-static wrist strap, I didn't see one of these in the box, so either I got jipped or it says it isn't included somewhere or? Anyway, I'm happy with it.
