The felt fabric lets you lay out a 27-1/2" x 21" puzzle with up to 1000 pieces (small roll) or a 46" x 32" puzzle with up to 2000 pieces (large roll), then roll it up on the large-diameter tube and strap it, holding the pieces in place for transport or storage.
Each puzzle roll includes a felt sheet, a tube for rolling (3-1/8" dia.for the small, 4-3/16" for the large), and straps to keep it all together.
Made in Canada.
