How many cards does it hold?

It has six card slots, three slip pockets, one zip pocket and an ID window. That suits a light carry but not someone who keeps a dozen cards.

Yes. It is made from 100% leather sourced from tanneries that meet high environmental standards, per the product listing.

Will it fit in a small purse?

It is a medium zip-around wallet at 5.25 by 3.5 by 1.25 inches, so it fits most everyday bags but takes more room than a slim cardholder or flat bifold.

What comes in the box?

The wallet itself. The listing does not mention a dust bag or gift box.

Is it the same as the full-price Michael Kors wallet?

It is an outlet model, so expect a simpler interior layout than full-price Michael Kors wallets even though the leather and hardware look similar.

Is this wallet worth buying over a cheaper zip-around?

You pay for the leather, gold-tone hardware and the Michael Kors name. Cheaper zip-arounds often use thinner leather and fewer interior pockets; this one has six card slots, three slip pockets, a zip pocket and an ID window.
