The Celine Seau Drawstring bag was first introduced in the Spring Summer 2012 Collection. It's a fairly large drawstring bag, the length approximately 18" with a base of about 13" judging from the pictures. It is only starting to hit stores now. The Seau can be worn as a shoulder bag mostly and can likely hold all your essential items.
The Seau in single leather color will retail about $2,300USD in stores.
