Craft Stax - Combo Tray Set This combo set includes six stackable frosted plastic trays that combine to create three storage boxes -one large and two medium.

Designed with die cutting in mind, these slim trays are ideal for holding tiny die templates or cut pieces to keep all your projects both handy and safe, as well as portable.
