Is there a minimum or maximum number of contributions for each Fondfolio?

We’ve set a minimum of 12 contributions, just so each book has a healthy thickness 🙂 and there’s no maximum — our unique design allows for an infinite number. Most Fondfolios tend to receive ~ 20 – 40 contributions, on average. The most we’ve ever seen collected was 244, but generally we think quality is much more important than quantity.
