I use eye glass case similar to that pictured from Dollar Tree (everything is a $1). Great place for you to stock up on the cases and they have many colors, I have a pink one and purple one. It just holds everything I need nicely, but things do roll around inside of it. I would love to see you make these and sell them. You obviously have many buyers just right here in the forum. Keep my name handy and let me know when you have some to sell.
