At Binding101 you can buy half size 3-ring binder mechanisms online and use them to make your own custom binders, unique swatches, journals, and so much more! These small ring binder spines are built specifically for a half-sheet of letter size paper, which measures 5 ½\" wide and 8 ½\" high. This is the exact measurement if you were to pull a regular piece of paper out of your printer and fold it in half, hence the name: half size! Packaged in a box of 50 pieces, you can choose ring binder hardware in several different ring sizes from as small as 1\/2\" for a thin 1\/4\" stack, up to as thick as 2\" for a thicker 1 ½\" stack. Each mechanism features 3-rings for a traditional look, with the spacing adjusted to 2 ¾\" between the rings. They feature boosters, which are the \"ears\" on each end that make opening and closing the rings easy and effortless, as well as a hole between the outside rings and the boosters that is the perfect fit for use with our binder rivets\u0026lt; to attach the mechanisms to a material of your choice. You will also need a rivet setter tool to bind the rivets and your mechanism firmly to the material of choice. Many customers choose to use a 90 point or so thick custom chipboard sheet. Every application is unique, and we would love to see your creations; you can email photos of your finished projects to \u003ca email href=\"mailto:{{config%20path=\" ident_general=\"\" trans_email=\"\"\u003e{{config path=\"trans_email\/ident_general\/email\"}}\u003c\/a\u003e.
