Provided are a liquid storage and release device and a pen comprising the device. The liquid storage and release device comprises a tube shell (), a capsule-like liquid container (), a piercing component () and a piston rod (), wherein the tube shell () is open at one end and closed at the other end, and the interior thereof is a tube cavity (); the capsule-like liquid container () and/or the piercing component () is/are slidably arranged in the tube cavity (); one end of the piston rod () is slidably arranged in the tube cavity () of the tube shell (), and the other end of the piston rod () is provided with a liquid release opening (); and the piston rod () is provided with a liquid channel through which the liquid release opening () is in communication with the tube cavity (). When the piston rod () slides towards the interior of the tube cavity (), the capsule-like liquid container () and the piercing component () apply pressure to each other under the action of the piston rod (), so that the piercing component () pierces the capsule-like liquid container () so as to release the liquid pre-stored in the capsule-like liquid container ().

Embodiments of the invention are directed to quick-assembly, articulating easel that moves from a planar orientation to an extended orientation with minimal manual manipulation. The easel components are movably interconnected, both in a compressed position during storage and in an extended position after assembly. The opposing writing surfaces of the easel may be oriented in upward positions parallel to the upward-facing bottom tray when in the compressed and/or disassembled position. Based on disengaging at least a portion of the interconnected easel components, such as by raising at least a portion of the easel components in an upward direction, the opposing writing surfaces may then be shifted in orientation to provide outward-facing writing surfaces in the assembled easel position. The articulating legs may then follow an arcuate curvature in travel between the various positions.

Embodiments of the invention are directed to a roller ball marking instrument for use with paint, a method for assembling the roller ball marking instrument, and a system for delivering paint. The body of the marking instrument includes a reservoir for storing paint. The body is coupled to a fibrous roller ball via a retaining ring. The roller balls sits within a partially-enclosed cavity in the center of the retaining ring. A least part of the roller ball protrudes through an opening in the retaining ring. Paint in the reservoir moves first through an opening at one end of the body and then through an open center of the retaining ring. The paint is transferred to the roller ball. The roller ball rotates freely within the cavity of the retaining ring and transfers the paint to a writing surface.

The present invention provides dissolvable films for customizing art materials, such as inks, paints, and modeling doughs. The invention also provides methods and kits for delivering artistic effects to art materials. The dissolvable films comprise one or more cellulose compounds, propylene glycol, glycerin, and one or more artistic components. The dissolvable film imparts an artistic effect following administration of the film to the art material. In exemplary embodiments, the artistic components of the film comprise one or more colorants which provide a coloring effect. A kit for delivering one or more artistic effects to an art material includes dissolvable films of various colors and shapes, and one or more art materials, such as ink, paint, or modeling dough.

The present invention relates to moldable sand compositions, methods for making the moldable sand compositions, and methods for using the moldable sand compositions. In a particular embodiment, the moldable sand composition comprises between about 70% to about 95% sand, between about 5% to about 30% water, a polar polymeric resin, a crosslinking agent, and a humectant. In an exemplary embodiment, the composition contains no oils, waxes, glycols, or rubbers. The composition is capable of becoming hardened over time in order to maintain the achieved shape, and can be re-wetted and molded again after becoming hardened.
