Systems and methods for dispensing solid and liquid materials

A device for dispensing a liquid material, the device comprising:

• a housing having an interior side, an exterior side, and a circumferential edge, wherein the interior side defines an inner cavity configured to accept an replaceable cartridge containing the liquid material, wherein at least a portion of the exterior side of the housing is flexible or includes a compressible element, and wherein at least a portion of the exterior side is configured as a grip;
• a buffing element;
• and
• at least one valve comprising a first end extending within the cartridge and a second end located at the buffing element, wherein the at least one valve is configured to dispense liquid material from the cartridge, through the at least one valve from the first end to the second end and to the buffing element,
• wherein the buffing element is releasably attachable to the housing, and
• wherein the at least one valve is a self-sealing valve, and configured such that an applied pressure on the at least the flexible portion of the housing or the compressible element forces the interior side of the housing to impinge on and compress the cartridge, wherein the cartridge compression forces the liquid material from the housing to the buffing element.
