Very nice quality, as described and great size. Not as heavy as my previous all leather purse. No zipper, has magnetic fastener inside and a flap with twist to lock closure. Adjustable strap. Beautiful color. Would definitely buy again in black as I’m fairly certain with proper care this purse will last for years.
