The present invention relates to a photocrosslinkable cosmetic composition, comprising in a physiologically acceptable medium: at least one photocrosslinkable urethane (meth)acrylate compound P1 comprising at least one structural unit: (I) at least one photocrosslinkable urethane (meth)acrylate compound P2 comprising at least one polyether chain, said compound having a molar mass greater than or equal to 1000 g/mol, at least one film-forming polymer P3, at least one photoinitiator, and at least one volatile solvent chosen from acetone, ethyl acetate, and propyl acetate, said solvent being present in said composition at a content greater than or equal to 20%, preferably greater than or equal to 30%, by weight in relation to the total weight of said composition, wherein the ratio of the total mass of P1 and P2 to the total mass of P3 is less than or equal to 4.0. ##STR00001##

A bracelet or flexible band comprised of a flexible member that on one end is interconnected to a knife and on another end, is connected to a sheath that selectively receives the knife in the locking fashion. When needed, the knife is rotated within the sheath to facilitate release thereof from a lock that is integral with the sheath. Once removed from the sheath, the knife can be used for self-defense, cutting rope or cord in an emergency situation, or for general utility cutting tasks.

A multifunctional portable tool is provided, which includes a housing; a motor received in the housing and having a first output end; a pump head movably received in the housing and having a driven shaft that is connectable with the first output end; and a first reset mechanism disposed between the motor and the pump head. The multifunctional portable tool has a first working state in which the driven shaft of the pump head is connected with the first output end of the motor so that the pump head and the motor together function as a pump, and a second working state in which the pump head is driven by the first reset mechanism to move away from the motor until the driven shaft of the pump head is disconnected with the first output end of the motor.

The polishing and shaping nail file, comprising a flat glass file body advantageously with an elongated shaped plate, one side of which has a roughened surface with a roughness ranging from 10 to 120 m with a chemically etched micro-structure for nail shaping. The active surface on the opposite side of the file body is adapted for nail polishing and completed by a metal grid preferably composed of Chrome (Cr) or Titanium (Ti), which is formed by separated protrusions of circular facets with a thickness ranging from 0.5 to 2 m, and with a diameter from 1.5 to 3 m.
