Abstract: A synthetic resin pen unit has a cylindrical outer annular member with inwardly extending bent and straight members. Each bent member has a base portion extending from the inner wall so that it is inclined with respect to a phantom line connecting the base of the bent member to the central axis of the cylindrical member. Ink grooves are formed between the inwardly extending members. The flexibility of the pen unit is a function of the percentage of bent members so that by proper selection and arrangement the pen characteristics can be optimized.

One of the sheets has two sets of holes that are covered by a removable strip of liquid-impervious material secured on that sheet. The size of the holes is such that there is no substantial passage of the liquid through the holes after the strip has been removed until the container is subjected to a compressive force that results in streams of liquid passing out of the holes. The spacing between the centers of the sets of holes is an interpupillary distance. A hand strap can be mounted on the other plastic sheet.
