Abstract: A writing instrument may be capable of preventing dye deposition to a pen core and highly achieving both inhibition of ink discoloration due to the dye deposition and improved writing feeling without reducing writing performance. Such a writing instrument may be equipped with a pen core and loaded with a water-based ink composition, wherein the water-based ink composition contains colored resin particles formed by polymerization of a monomer comprising at least cyclohexyl (meth)acrylate, enclosing a basic dye, an oil-soluble dye or an acid dye, and further contains an anionic surfactant.

Abstract: A writing implement is configured to dispense material onto a work surface. The writing implement includes a body having a first end, a second end, and an inner surface. The writing implement also includes a nib coupled to the first end. The nib is configured to allow the material to be dispensed onto the work piece. The writing implement further includes a pressure regulating assembly coupled to the body. The pressure regulating assembly and the inner surface define a cavity configured to hold the material. The pressure regulating assembly is moveable relative to the body in response to a pressure change within the cavity.

Abstract: A marker board system having a dark colored, low hardness, low surface energy solid silicone sheet to wet to a vertically oriented high surface energy substrate on a smooth, flat back-side of the solid silicone sheet. A front-side of the solid silicone sheet is able to be written upon by brightly colored marker ink. The brightly colored marker ink is able to be easily erased from the front-side of the solid silicone sheet after being written upon the front-side of the solid silicone sheet. The front-side is roughened to diminish beading of the brightly colored marker ink when written on the front-side.

Abstract: A substrate usable with a double-side adhesive strip to suspend the substrate to a wall surface. The substrate can have one or more access holes located within an outer perimeter of the substrate. Each access hole has an inner perimeter inwardly of the outer perimeter that is sized and shaped to allow a tab of the double-sided adhesive strip to be extracted through the inner perimeter, after the substrate is suspended on the wall surface. Various articles can attach to the suspended substrate, such as through magnetic attachment, a hook, or a shelf.
