Rayson 3:1 Pitch Plastic Spiral Binding Coils, 7/16" Diameter, 11.1mm, Binds Up to 80 Sheets, Letter Size (8.5" x 11"), Black, Pack of 100

I bought one of the less expensive spiral binding machines a few years ago, and have been surprised at how often I use it. These coils are great for making small booklets. They're durable, easy to use, and dependably uniform. Very high quality. Five stars all the way.

Works great

As described. good quality for the price.

Use these a lot. I'm a repeat customer

These have been good value. They are easy to spin through the holes if you cut the leading edge at a sharper angle. We have made over a hundred booklets at this point and have had no issues so far.

These are very good spirals and I’m sure I will find many uses for them. I docked one point because these were listed as white when I ordered them, but are actually black. There’s no point in exchanging them since there is no longer a white available. The quality is good and 3:1 spirals are a bit hard to find, so I am still glad to have these.

Bought these in February this year and have used them for many books/manuals I have printed at home this year. This is the largest size for a 3:1 pitch binding machine I can find on Amazon. Buying direct from stores online is much more expensive. There is a review below that states these are too short for 8”x11” letter sized paper and they will be if you try to use them with a 4:1 or 5:1 pitch binding machine. For a 3:1 pitch these are perfect for A4 sized paper and I cut them for 8”x11” letter sized paper. Sad that the copy center the customer below consulted did not know how to recognize this difference in pitch sizes for binding. Good purchase.

I have been through 2 boxes of thee and will be buying again soon. I recommend these for the do it your selfer.

Parfait pour relier des dossiers manuellement. Coupable avec un simple ciseau.

Ottimo materiale, utilizzo per rilegatura fogli e cartoncini, il movimento a spirale è di facile montaggio con i fori praticati dalla perforatrice adatta. Ho applicato la spirale su varie dispense con un buon risultato.

perfecto

Good

Très facile d’utilisation je recommande ++
