Thank you for viewing. These are KOLO binding posts, famous for their use in albums. There are two long posts and six short posts. The photos show them in their original bags, but please disregard the bag's labeling and refer to the ruler for the actual sizes. Each post can be opened on one side with a flathead screwdriver, and they are sized to hold paper punched with a hole punch. Perfect for binding scrapbooks or creating menus. They have hardly been used, but I will sell them to someone who understands they are used items.
