ICEWRAPSFlexible Gel Cold Pack for Therapy - 11"x14" Standard Knee, Joint, or Back Gel Ice Pack - Includes Free Bonus Cover

Can someone who has purchased this ice pack within the past several months (2019) confirm that it does include a cover? Thank you!

How many ice wraps are in the box?

After using for 20 minutes and returning to freezer, how soon is it ready for use again?

Can I microwave this to make it hot?
