Ultra Pro TopLoading Combo

The Ultra Pro Toploading Combo is a bundled package of trading card storage and protection products for standard-size collectible cards. It includes soft sleeves and rigid toploaders, and some versions also come with a storage box. 
Included items 

Toploaders: These are rigid, super-clear, PVC plastic protectors with 3" x 4" outer dimensions, designed to safely store standard-size cards.
Soft sleeves: Often called "penny sleeves," these are made from non-PVC, archival-safe, acid-free polypropylene film. They provide an initial layer of protection against scratches and damage.
Storage box: Some versions of the combo pack include a clear polypropylene storage box with a self-locking lid.
