         2 . The cup of  claim 1 , wherein the at least one retention member includes a plurality of recesses extending inwardly into the inner sidewall in an axial pattern. 
     
     
         3 . The cup of  claim 1 , wherein the at least one retention member includes a plurality of recesses extending inwardly into the inner sidewall in a radial pattern about the periphery of the inner sidewall. 
     
     
         4 . The cup of  claim 1 , wherein the at least one retention member includes an upper ledge surface that cooperates with the inner sidewall to define an undercut region. 
     
     
         5 . The cup of  claim 1 , further comprising a secondary retention member disposed on the inner sidewall of the cup body and extending into the cup cavity. 
     
     
         6 . The cup of  claim 5 , wherein the secondary retention member comprises an elongated notch having a first end having a first width, a second end having a second width, wherein the second width is greater than the first width thereof. 
     
     
         7 . The cup of  claim 6 , wherein the elongated notch includes an extension extending inwardly from the inner sidewall into the cup cavity and a notch contact face extending generally perpendicular to the extension. 
     
     
         8 . The cup of  claim 7 , wherein the extension and the notch contact face cooperate to define a channel region. 
     
     
         9 . The cup of  claim 1 , further comprising a floor member, the floor member defining an opening surrounded by a frustoconical surface. 
     
     
         10 . A cosmetic product container comprising:
 an inner body having a first end and a second end and defining a container cavity;   a cup adapted to be at least partially disposed within the container cavity, the cup including:
 a cup body having a first body end, a second body end, and an inner sidewall forming a cup cavity, and 
 at least one retention member disposed on the inner sidewall of the cup body and extending into the inner sidewall, the at least one retention member extending a width around a periphery of the inner sidewall; and 
   a cosmetic substance having a first end, a second end, and an elongated body therebetween, wherein at least a portion of the elongated body is disposed within the cup cavity.   
     
     
         11 . The cosmetic product container of  claim 10 , wherein the at least one retention member includes a plurality of recesses extending inwardly into the inner sidewall in an axial pattern. 
     
     
         12 . The cosmetic product container of  claim 10 , wherein the at least one retention member includes a plurality of recesses extending inwardly into the inner sidewall in a radial pattern about the periphery of the inner sidewall. 
     
     
         13 . The cosmetic product container of  claim 10 , wherein the at least one retention member includes an upper ledge surface that cooperates with the inner sidewall to define an undercut region. 
     
     
         14 . The cosmetic product container of  claim 10 , further comprising a secondary retention member disposed on the inner sidewall of the cup body and extending into the cup cavity. 
     
     
         15 . The cosmetic product container of  claim 14 , wherein the secondary retention member comprises an elongated notch having a first end having a first width, a second end having a second width, wherein the second width is greater than the first width thereof. 
     
     
         16 . The cosmetic product container of  claim 15 , wherein the elongated notch includes an extension extending inwardly from the inner sidewall into the cup cavity and a notch contact face extending generally perpendicular to the extension. 
     
     
         17 . The cosmetic product container of  claim 16 , wherein the extension and the notch contact face cooperate to define an undercut region. 
     
     
         18 . The cosmetic product container of  claim 10 , further comprising a floor member, the floor member defining an opening surrounded by a frustoconical surface. 
     
     
         19 . A method of assembling a cosmetic product, the method comprising:
 providing a cup including a cup body having a first body end, a second body end, an inner sidewall forming a cup cavity, and at least one retention member disposed on the inner sidewall of the cup body and extending into the inner sidewall, the at least one retention member further extending a width around a periphery of the inner sidewall;   inserting a cosmetic substance having a first end, a second end, and an elongated body therebetween into the cup cavity of the cup such that at least a portion of the cosmetic substance enters the at least one retention member; and   at least partially disposing the cup within a container cavity of an inner body.   
     
     
         20 .
