Is ostrich leather durable for daily use?

Yes. Ostrich is one of the tougher exotic leathers because the quill follicles give it a dense surface. It resists scuffing better than smooth calfskin, but it should be kept away from water and conditioned occasionally.

How does this compare with a smooth-leather designer wallet?

The ostrich hide gives it more texture and a rarer look than smooth calfskin, and it tends to hold up better against scuffs. It is also thicker and less pliable, so it sits bulkier in a pocket.

A continental clutch is sized to hold a phone, cash and cards together. Very large phones may be tight once the wallet is full.

Does the zip closure keep coins secure?

The zip runs around the wallet and closes the coin pocket along with the main compartment, so loose change stays contained.

How should I care for ostrich leather?

Wipe it with a dry cloth, keep it out of prolonged sunlight and rain, and store it in its dust bag. Use a conditioner made for exotic leathers, not a standard leather cream.
