Abstract
Abstract A blister card package has a product with an enlarged portion, and a conforming blister. Interference between the resilient blister and the enlarged portion retains the product in the package when the product is subjected to moderate removal forces, such as gravity. The product may also be returned to the package for resilient retainment and storage.
