I bought this to use at work, so I needed something professional enough for the setting. I love it because it's fun enough to make people smile, but it doesn't come across as immature.
The pages are pretty standard thickness (not super thin), as i've come to expect from Sanrio (compared to say, non-big-branded merch). I wish there were more pages in it, but the colors are vibrant and crisp and clear. Worth the cost.
