Provided is a liquid storage member for coating tools which successfully reduces plastic consumption and reduces environmental loads, by making use of materials based on paper in place of plastics such as polypropylene that has been used for liquid (e.g., ink) storage members. A liquid storage member for coating tools having at least three layers of a paper base laminate composed of an inner layer made of paper base material, and a middle layer of a metal layer or a silica deposition layer, formed on the outer peripheral side of the inner layer; and an outer layer made of the paper base material formed on the outer peripheral side of the middle layer, wherein the paper base material of the inner layer has a density of 0.8 g/cm.sup.3 or more.

A marker and stamp system embodied in a double-end device is provided. The device includes a marker end and an opposing stamp end. The stamp end enables the creation of clear and concise group presentations/instructions through the uniform application of predetermined symbols via a stamp applicator portion and marking template, while the marker end facilitates the presentation of tailored, free-hand markings via application of a marker nib.

A liquid storage includes at least three layers, an inner layer made of paper base material and an intermediate layer of a paper base laminate having a metal layer or a silica vapor deposition layer formed on the outer surface side of the paper-based inner layer, and an outer layer made of paper base material formed on the outer surface side of the intermediate layer. The paper base laminate is wound into a spiral shape and on the outer surface side of the intermediate layer, the outer layer is also wound into a spiral shape. A polyolefin resin-containing adhesive layer lies in between the inner and intermediate layers and/or between the intermediate and outer layers.
