Multibey A5 6-Ring Rose Gold Binder Ring Mechanisms 2Pcs, Round Ring Binding Spines Combs Replacement for A5 Loose Leaf Notebook (A5-30mm Ring Diameter, Rose Gold)

The size is comparable to happy planner classic size. Good quality. I’m very satisfied with the product.

It is very sturdy and was easy to install.

So, I like these ring sets, and one of them worked great for my needs. However, the screws are easily stripped... which was an issue when I was making a binder for them to go into, and as such had screwed and unscrewed the rings a few times (to make sure that the chipboard I was binding it to still bound well as I added decorations). I screwed and unscrewed it probably 7 times before it suddenly stopped working. It turns out that the tip of the screw got stripped, so it wasn't catching the bolt part.Frustrating, yes... but I tried to find replacement screws. Nearly *everything* I can find is 4mm diameter screws... when this ring set apparently takes 3mm diameter screws. I'm still trying to find replacement chicago screws for this (especially in rose gold, but at this point I'll take any finish!).I'd give this set 5 stars, but the quality of the screws knocked it down a star, and the fact that the screw size they used is so difficult to find, that's another star docked. If anyone can direct me to where I can find 3mm diameter chicago screws (especially in rose gold), that would be super helpful!

I used this ring mechanism to replace the silver colored ones in a Moterm A5 planner. replacement was simple, needing only a thin coin or a flat head screwdriver to remove the old one and put in the new. Improved the look of the planner.Rings are very tight, no gaps and aligned perfectly. Customer was happy.
