Lost blue silicone medical wristband with allergy information, misplaced in a friend's bathroom in East Midlands.

I accidentally misplaced my medical wristband while I was visiting a friend's house in East Midlands. It is a blue silicone band that has my allergy information printed on it. I remember taking it off to wash my hands and I think I left it on the bathroom counter. If anyone finds it, please contact me as it's crucial for my health to get it back.
