Sigel Conceptum Flex organiser system A5 - Review

Sigel Conceptum Flex organiser system, A5 - Review A German book-by-book system, democratically priced, but with some functionality issues. System product page: https://www.sigel-office.com/de/busin... All of my reviews are independent and are of products that I have purchased myself. To help defray those costs, you can donate as little as € 1 to me at https://ko-fi.com/grahamrhind . The more that is donated, the more reviews I can post. You can also leave comments if you want to see a review of any specific product. Thank you.
