My go to bag/ bag insert now
I use it to carry my tiny card holder, car keys, and other essentials, and it easily fits into any of my bags or backpacks. When I park, I can simply grab it without having to take my entire gym bag or backpack with me while running errands. Plus, it looks fantastic on its own as a small shoulder bag! But make sure you purchase a strap to carry it on your shoulder. I think those sold separately.
