This baby pink planner is in an A6 size and it's brand new as I bought this in the wrong size. It measures approx 12cm x 19cm. It has a snap button closure so it's really secure! It has 6 rings in total and can hold quite a lot of planner paper which u can easily find online or in stationary stores :) It also has many compartments in the front and back! There's also two elastic parts for holding pens or pencils (shown in photo). This is great for any age too!
