The RGS Group Jigsaw Puzzle Roll-Up Mat Up to 3000 Pieces features an extra-large workspace progress protection kit. A specialized non-slip felt mat surface grips massive projects firmly. The broad 1250mm x 930mm template supports high-capacity layouts cleanly. Users build directly on the mat and roll it away. An inflatable internal support core prevents piece distortion completely. Three durable velcro fastening straps keep the roll tightly compressed. It accommodates standard RGS Group puzzles up to 5000 pieces.
