Abstract: A straw case is provided that may store a flexible or collapsible straw. The straw case includes a strap member that may be received by a slot member in a lid coupled to a tumbler. The strap member may be releasably coupled to the straw case via at least one pin. Thus, the strap member can be selectively decoupled from the straw case, thereby allowing the strap member to be fed through the slot member so that the straw case can be decoupled from the lid. Alternatively, the user can decouple both ends of the strap member from the straw case, thereby decoupling the straw case from the lid without removing the strap member from the slot member.
