There's still plenty of room even with a kids' camera inside. The strap is about 80cm long. We've made it longer so you can use it for as long as possible, so please adjust it by tying it. The depth and sides are about 3cm, but the opening is wide. It's about 12cm tall and about 10cm at the opening. I've knitted it carefully, but it's a handmade item by an amateur, so thank you for your understanding. (୨୧•͈ᴗ•͈)◞♡
