A dry erase ink for a writing instrument. The dry erase ink includes, as the main organic solvent, a solvent selected from the group consisting of n-propyl acetate, isopropyl acetate, or mixtures thereof.

A combination glove and marking device where the marking device is built into the forefinger portion of a glove and the applicator tip extends through an aperture located at the tip of the forefinger of the glove so that a user can mark an item such as a bingo card by simply pressing down with his or her forefinger. In an alternate embodiment, the marking device can be attached to the user's finger by one or more straps. The marking device includes an ink reservoir that is refillable by the user.

An electronic board includes a writing board, a sensor sheet including X parallel electrode lines and Y parallel electrode lines, a chassis to which the sensor sheet is bonded, a corner reinforcement plate disposed on the rear side of the chassis and supporting the chassis, and a bezel. The writing board, the sensor sheet, and the chassis are successively disposed in the mentioned order and are fixed together into an integral sensor unit. The corner reinforcement plate includes a top surface portion, a first lateral surface portion, a second lateral surface portion, and a chassis retaining portion. The sensor unit is sandwiched between the chassis retaining portion and the bezel.

A writing implement is provided which is designed to draw lines using capillary action, wherein the width of the line can be freely adjusted while the line is being drawn and it is possible to draw lines of almost the same width at the beginning of the use of the writing implement as at the end of use. A felt-tip pen 1 is provided with an ink reservoir 11, a collector 17, and a core 29 for drawing by capillary action the ink that has been dispensed by the collector 17, dispensing the drawn ink from the tip, and adhering same to a paper surface. Even in repetitive writing, the rate of variability in the width of the lines drawn at the end of use with respect to the width of lines drawn at the beginning of use is 10% or less.

A nib for a refillable free ink writing felt pen includes a body and a dry ink tank including dry ink, the dry ink tank being delimited by the body of the nib and a dry ink tank wall including a breakable portion.

A method for preparing a thermochromic water-based gel ink composition, as well as a thermochromic water-based gel ink composition thereof comprising a specific monocarboxylic or polycarboxylic acid. A writing instrument, such as a ballpoint pen, a brush pen, a marker, a highlighter, and a felt pen, comprising a thermochromic water-based gel ink composition according to the disclosure.

Provided is an aqueous ink composition for a writing instrument which is excellent in a drying property of drawn lines and a low temperature stability of the ink while inhibiting the pen tip from drying and which prevents the drawn lines from causing feathering and strike-through. The aqueous ink composition for a writing instrument described above contains at least a colorant, trimethylglycine, pentaerythritol, 10% by mass or less of a water-soluble organic solvent and water.

Provided herewith is a marker that has multiple colors and retracts and seals the ink reservoirs. Also provided is a method of selecting a color.

A combination spinning top including a multiplicity of petals removably retained at spaced apart locations on a circumferential end wall of a central round body to give the combination spinning top the appearance of a flower and to provide balance to enable the combination spinning top to spin on a tip for a longer period of time than it would spin without the petals. Each of the multiplicity of petals retain a writing instrument, the writing instrument also serving as an attaching arm to attach a respective petal to the central body of the spinner top.
