Relaclife Electromagnetic wave shield 68 x 48 cm 100% pure silver This is an outlet item, and there are traces of the machine stitching having been undone (it starts from the area indicated by the ↓ in the image - it's difficult to see). I used it for only 3 months, covering a Wi-Fi router. I don't know why, but the color started changing and developing stains soon after I started using it, and it doesn't look very clean. It's best not to wash it, so I only hand-washed it once with water the other day (I didn't use a washing machine for spin-drying either). I'm sorry, but I'm not accepting any discounts.
