Channel 420 may be a hollow cylinder, having a needle-like shape. Channel 430 may allow for the release of the nail polish in the middle of the bristles, after the brush base. The brush base itself may not be exposed to the nail polish which may be generally flow towards a distal end of Brush 410 due to gravitational forces and due to the position of Capsule 400 when nail polish is deployed. In some exemplary embodiments, several Channel 430 may be utilized to provide for a relatively even distribution of nail polish over different portions of the Brush 410.

[0068] Capsule 400 may comprise an Embedded Identifier 460 in the form of a barcode that is readable by a barcode reader. In some exemplary embodiments, a barcode reader may be utilized to read the barcode or other printed matter on Capsule 400 to identify content of Capsule 400 and properties thereof.

[0069] In some exemplary embodiments, additional embedded identifiers may be utilized. Wireless or wired communication methods, such as Near Field Communication (NFC), Bluetooth, or the like, may be utilized to allow communication between an identification module embedded within the Capsule 400 and the device. In some exemplary embodiments, wired communication methods may be utilized in which a direct contact between circuits is utilized to communicate between the different modules. The direct contact may also be used to provide power supply to the embedded identifier module. Additionally or alternatively, a separate power source, such as a battery, may be included in Capsule 400, e.g., as part of the embedded identifier.

[0070] In some exemplary embodiments, the embedded identifier may provide one or more of the following information items: name or unique identifier of nail polish brand; name or unique identifier of nail polish color; name or unique identifier of the material; one or more nail polish properties (e.g., surface tension level of the nail material, viscosity level of the nail material, or the like); one or more brush properties (e.g., bristles density, bristles length, bristles width, bristles flexibility level, or the like), initial volume of nail polish, or the like. In some exemplary embodiments, information conveyed to the nail polish application device via the identifier may affect the manner in which the device applies the nail polish. The device may employ different coloring patterns in view of the different properties of the nail polish and of the brush.
