This is how it works: You do the puzzle directly on the non-slip felt base. To roll it up, place the previously assembled plastic tube on a narrow end of the felt base and carefully wrap the felt with the puzzle tightly around it until both are completely rolled up. Now all you need to do is secure the roll with the rubber bands provided and you can safely move your puzzle to another location and store it in a space-saving way, preferably lying flat. The high-quality plastic tube provides extra stability and makes it easier to roll up. Item is assorted - you will receive a version at random. Price per piece.
