ELEGANT & SOPHISTICATED WITH THE PERFECT SIZE AND STYLE!
Color: Black
I love the unique design of this clutch! There's THREE ways of carrying this clutch! 1) I can add a strap to make it a crossbody purse, 2) It has a wristlet strap, 3) Plus, the best is the long strap on the side of the clutch that allows me to place my hand through it and securely hold it in such a fashionable way! I get tons of compliments on it. I bought two, one in red and one in black. The leather-like material is durable, and the fixtures stay gold and do not fade. I use it daily, so it gets worn out within a year. The rubber edges would unfurl or get cracked. The zipper can break if you stuff the clutch too much, and the edges do get frayed easily, but for the cost, it's worth it! You can dress it up or wear it casually.

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.
