The Ultra PRO Playmat and Artwork Tube is perfect for storing your standard size playmats, transporting artwork or documents, or for storing maps and other small collectibles. The tube is 15 inches in length and 2 inches in diameter. The black rubber caps have a snug fit that will not fall off, and the squared design will keep your tube from rolling away! Note: All standard size Ultra PRO Playmats and Breaker Mats fit in these tubes, including those with stitched edges. Playmats from other sellers which are made with a thicker material may not fit. We recommend measuring the diameter of your rolled playmat prior to purchase.
