Not tight enough of a grip on phone inside the sleeve, as a result my wife’s phone slipped right out and cracked on the ground

While the sleeve option is nice for those that don't want to use a case on their phones, in my opinion it would be nice to have some sort of snap closure or similar to secure the phone from falling out of the sleeve by accident.

This sleeve is really nice, it fits the phone well, but unless you pack the card holder full of cards they could slip out.

when the case was off) that the phone wouldn’t fall out if I held it upside down.
