Roll your puzzle is an ideal work surface & storage system for unfinished & finished puzzles. It is made from thick, high-quality non-slip felt material, & will hold pieces in place, whilst allowing you to move pieces around when necessary. To use, simply assemble your puzzle on the felt sheet & when you are finished for the day & want to clear it away, inflate the tube & carefully wrap the puzzle & felt working surface around the tube. Secure it with the rubber bands supplied. You can then store the puzzle away for another day. The Ravensburger Roll your Puzzle comes folded inside a sturdy box. If you find the felt does not lay flat when you open the box, then you can iron it carefully, using a warm iron, with a clean t-towel between the felt material & the iron. This will easily remove any creases to give you a super-smooth puzzling surface. The Roll your Puzzle felt surface measures 100 x 66cm, so is large enough for most commercial puzzle sizes up to 1500 pieces.
