I was introduced to the card keeper organizer when a client purchased several to organize her extensive collection of note cards. Overall I liked the product and would recommend them to others.  Here are the pros and cons:

Pros:

• Attractive clear container
• Stores all your notecards in one location
• Separator tabs allow for labeling categories

Cons:

• May not be big enough depending on an individual’s card collection
• May be too big depending on an individual’s card collection
• Slots may not accomodate all sizes of cards
• Latch can be difficult to open

This organizer is best for someone who enjoys purchasing cards throughout the year and wants a place to store them.  I purchase cards on an as-needed basis and send them immediately, so an organizer like this would not be as necessary for me.  I do on the other hand keep blank note cards, however feel this level of containment is not necessary for them. If you maintain a small collection of cards in a variety of categories, then this organizer is worth taking a look at.
