Awesome bag!
Color: Silver
I LOVE this bag! I use it daily. My only wish is that it was larger, although it does hold much more than you might think. I tried to post a pic of the inside and all it holds, but the app won't let me right now. I'll check back later. Until then, the list includes... Credit, check, and insurance cards (all 8 of them), 2 pens, A pen light, Fingertip spray bottle for alcohol, Mirror, ID, Several business cards, Folding phone stand shaped like a credit card, Charging cord, Charging battery (a hefty one with qi charging), Prescription sunglasses inside a box for protection, A magnifying card with light. My phone is too big to fit in the zipper compartment (Note 10+), so I usually use a lanyard. I COULD fit it into the main compartment, but it's tight. I attach my keys to the loop with the wrist strap. Otherwise they would scratch my phone if I choose to put it inside. An expanding bottom along with just an inch added to both the height and length would make all the difference for those needed items. If the owners/designers read this, I'd request a divider going lengthwise as well to keep my phone separate and protected. It doesn't have one, or a pocket for a large phone. I do believe, however, that the latest folding Razr or Samsung's Z-Flip would easily fit into the pockets provided with no problem.

Durable!
This is amazing!! I’ve had it for a year now and nothing has ripped or worn at all. (I use it pretty roughly) It’s very spacious, and great inside and outside material. And yeah it actually comes with a cute bear XD
