Can it hold a phone and a wallet?

It has credit card slots, so you can skip a wallet for cards. A large phone fits in most bags of this style, but check the listed dimensions before buying if you carry a big phone.

Does the strap come off?

Yes. The shoulder strap is detachable, so you can carry it by hand or on the shoulder.

Is the closure secure?

It uses a magnetic lock, which is fast to open but easier to pop open than a zipper. Keep valuables in an inner pocket in crowded places.

Will the light pink leather stain?

Light leather can pick up dye from dark denim and dirt from hands. Store it in a dust bag and keep it away from dark fabrics.

What comes in the box?

A dust bag or care card is not stated. Ask the store before ordering if that matters to you.

Is this bag worth it against other Michael Kors leather bags?

It offers a magnetic closure, card slots and a detachable strap in a seasonal color. Larger Michael Kors totes hold more but are heavier and less wallet-like. Choose this one if you want a light bag for short outings.
