These loose leaf binder rings at the 3" size are quite large - I purchased them to store embroidery floss bobbins for various projects. They are exactly what I was looking for and do the job. I like that the packaging is a flip-top cardboard box - safe storage before I need all the rings.
Good strong sturdy product. I only give a 3 because the diameter of the metal is to thick for what I need it for and will return it for a smaller diameter of the material. Overall size is good. Overall good product.
The bookrings are easy to open and close and securely stay in place/ locked. The rings are sturdy and the quality of the finish is superb. I am using the rings to hold my collection of Pandemic facial masks.
I needed rings to hold chart tablets on several easels in the classroom. I wasn't sure if the size would work but thought I would give them a try. Turns out they worked great. The size was perfect for my needs. Great item if you are a classroom teacher.
