A manual device including a first portion and a second portion. The second portion being at least partially fitted into the first portion and being moveable in translation relative to the first portion. The first portion having a first distal end while the second portion has a second distal end opposite the first distal end. The second portion also includes a locking device designed to prevent the first portion from moving in translation relative to the second portion only when, considered in the direction of gravity. The first distal end is arranged above the second distal end, and the locking device includes a chamber and a ball or equivalent accommodated in the chamber. The chamber is provided only in the second portion.

A composition comprising; a) at least one homopolymer or copolymer of vinyl acetate; and b) at least one softener.

An example dry eraser and associated systems and methods are described. The example dry eraser includes a body with a top wall, a bottom wall, a front wall, a rear wall, and first and second side walls. The body includes a hollow interior configured and dimensioned to receive therein a plurality of individual wipes. The top wall of the body includes an opening configured and dimensioned to dispense therefrom the plurality of individual wipes. The dry eraser includes an erasure material disposed on at least a portion of the bottom wall of the body.

A coating film transfer tool may include a casing that houses a feeding reel around which a transferable tape is wound and a winding reel; and a transfer head having a main body portion arranged in a front side which is one side of a front-rear direction of the casing to extend in a left-right direction perpendicular to the front-rear direction in a front end portion and provided with a pressing edge portion adapted for transferring the coating film to a transfer target surface. The casing or a base member housed in the casing may have a protruding tip that extends to the transfer head side and is connected to the transfer head. The protruding tip may press a part of an area including a center of the left-right direction of the main body portion to the transfer target surface side in the event of a transfer.

A mechanism of a daily commodity ejecting and retracting device includes an operating portion provided to rotate around a center line vertical to an axis line of a shaft tube in relation to the shaft tube between a first rotation position and a second rotation position. A rod portion is coupled within the shaft tube to rotate around a first axis line and is coupled to the daily commodity to rotate around a second axis line which is parallel to the first axis line. An eccentric position of the first axis line is set so that the daily commodity is immersed into the shaft tube via the rod portion when the operating portion is rotated to the first rotation position, and the daily commodity protrudes out of a leading end port of the shaft tube via the rod portion when the operating portion is rotated to the second rotation position.

A composition comprising; a) at least one homopolymer or copolymer of vinyl acetate; and b) at least one softener.

A moldable eraser kit includes a first silicone polymer, a second silicone polymer, an abrasive agent, a catalyst configured to catalyze a reaction between the first silicone polymer and the second silicone polymer at room temperature, and at least two containers such that the first silicone polymer, the second silicone polymer, and the catalyst are not all present in the same container. Also disclosed herein is a method of making an eraser including the steps of mixing a first silicone polymer, a second silicone polymer, a catalyst, an abrasive agent, and optionally one or more additives to form a mixture, the mixture being free of polyvinyl chloride. The method also includes molding the mixture to form a shape and curing the mixture in the shape at room temperature to form a molded eraser.

An example dry eraser and associated systems and methods are described. The example dry eraser includes a body including a top wall, a bottom wall, a front wall, a rear wall, and first and second side walls. The body includes a first hollow inner compartment configured and dimensioned to receive therein a cleaning fluid that is configured to be dispensed from the first hollow inner compartment via a nozzle disposed proximate to the front or rear wall of the body. The dry eraser includes an erasure material disposed on at least a portion of the bottom wall of the body.

A collapsible dual screwdriver assembly pliers or drive-pliers for short, comprises a pliers and two screwdriver assemblies, where the screwdriver assemblies are individually removably attachable in a stowed position and an extended position. In the stowed position each screwdriver assembly can provide compact storage of the tool as well as function as a portion of a handle for the other screwdriver assembly. In the extended position each screwdriver assembly can be used as an extended handle for the pliers, as well as, function as a multi-bit screwdriver individually.
