10 stuks bindkammen 30 ringen kam bindende stekels spoel bindmachine plastic spiraal boek binder voor leraar student documenten notebook bestand maken, gemengde kleuren, 1/2 inch

I bought these ring binders along with the 10 hole punch to spiral bind my colouring books, and they are perfect for the job, not too big. So much cheaper than getting the books bound by a stationer. The binding is so easy to use and they click together perfectly with a seamless join. I have no need to open the binding up to add more pages so cannot speak to this aspect.

Farben sind toll. Lassen sich leicht schliessen. Halten super zusammen.

Seems good quality haven't used yet though

machte Adventkalender. zufrieden

These are 30 holes for a4 but they can be cut down for other sizes. I have cut them down for b5 and have kept the bits for other sizes. The smaller pieces can be used for other folders using rings just at top and bottom. They are quite strong and easy to open and close so paper can be replaced as necessary. Colours are okay but very pastel, some stronger colours would be nice. But a very good buy.
