Colophon marbling tanks are vacuum formed with a single sheet of high impact ABS plastic. The seamless construction eliminates the need to repair leaking tanks common with wooden tank equivalents. These are designed with a self-draining "slop trough" which contains and disposes of freshly skimmed size, and the slop trough can double as a stand for the drain board when transferring freshly marbled sheets. Each tank comes with one drain board. Skimmers sold separately.
