Grounding Mattress Cover

Never received the free gift that was part of the purchase and the test pen which should have been included. How will I know if this has conductive fibers?

Took 11 days to receive the grounding mat. Was easy to set-up and appears to be of good quality. Haven't used yet and there was no conductivity pen included as stated in the attached set-up instructions. Since there was no included pen i wasn't able to test to ensure that there was conductive fibers. We will have to see if it does what it claims.

Got it recently and will start using ut today- looking forward tonit and hope it works as advertised. Only thing that i didnt like is booklet says “conductivity pennis included in the package” but i didnt get one with mine- i dont remember it saying had to be purchased or selected separately 🤷🏽‍♀️
