Here's how it works: You puzzle directly on the non-slip felt mat. To roll it up, place the previously assembled plastic tube at one narrow end of the felt mat and carefully wrap the felt with the puzzle around it until everything is completely rolled up. Now you just need to secure the roll with the included rubber bands, and you can safely transport your puzzle to another location and store it space-efficiently, preferably lying down. The high-quality plastic tube provides extra stability and makes rolling it up easier.
