Abstract: The present invention provides an ink-slab for calligraphy, wherein a hollow case is formed. A baffle partitions the space of the case into a water tank and an ink tank. Each tank has an opening. The openings of the water tank and the ink tank extend upwards to form necks and are installed slantingly along the direction of hair arrangement and ink scraping. Using so integrated but still separate design, the user can select to moisten a hair pencil with ink or dilute or wash it with water according to necessity. Hair arrangement will be more smooth and the scraped ink can be prevented from spilling out of the opening. An accommodation tank is formed in the case and a case cover is matched with the accommodation tank. Tissue papers can be placed in the accommodation tank to be taken along with the ink-slab. Concavity grooves are formed on the bottom edges of side walls of the cover for the accommodation tank. Hair pencils can be placed on the concavity grooves when the cover is placed upside down.

Abstract: A container assembly suitable for standing on a desk top or other flat surface to store office and other articles of daily use is built in a modular manner from individual structural elements arranged axially in series side by side. Each structural element consists of a prismatic body which has at least three longitudinal external walls and has a base, bounded by two longitudinal edges and two lateral edges, by means of which it stands on the desk top.The longitudinal edges of the base and the longitudinal edges of the external walls run parallel to the central axis of the prismatic body. At least one of the longitudinal external walls of this body forms a front face which is inclined in a lectern-like manner in relation to the base, and the prismatic body has on both sides a side wall which in each case runs perpendicular to its central axis.
