This is a handmade case for the Anshin Watcher. I've used it for about 3 years. It's made of canvas and has a window where the button is visible. I used a keyholder to attach it to the D-ring inside my child's school backpack. It's easy to take in and out with Velcro. However, I was worried about it falling out, so I kept it inside the backpack. There are some loose threads in places. The corners of the case show wear and tear, and signs of aging. I've decided to get rid of it because the Anshin Watcher cannot be reused once the contract is terminated. I hope someone who has one can use it.
