         4 . The cosmetic device of  claim 3 , wherein the recess and the drive shaft have corresponding shapes to prevent relative rotation between the drive shaft and the drum. 
     
     
         5 . The cosmetic device of  claim 1 , wherein the drum assembly includes a generally cylindrical drum, the drum including the abrasive outer surface and the deformable portion, and wherein the drum assembly includes a drive shaft and the drive system includes a drive member defining a recess, wherein the drive shaft is received within the recess. 
     
     
         6 . The cosmetic device of  claim 1 , wherein the abrasive outer surface includes a first portion having a first abrasiveness and a second portion having a second abrasiveness different from the first abrasiveness. 
     
     
         7 . The cosmetic device of  claim 6 , wherein the first portion includes a first visual indication of the first abrasiveness and the second portion includes a second visual indication of the second abrasiveness. 
     
     
         8 . The cosmetic device of  claim 1 , wherein the deformable portion is configured such that the abrasive outer surface and the deformable portion deform upon application of pressure during use of the cosmetic device on a nail of a user. 
     
     
         9 . The cosmetic device of  claim 1 , wherein the deformable portion includes a first portion having a first compressibility and a second portion having a second compressibility different from the first portion. 
     
     
         10 . The cosmetic device of  claim 1 , wherein the drum assembly is a first exchangeable drum assembly configured for removable and/or replaceable attachment to the housing, further comprising at least one second exchangeable drum assembly configured for removable and/or replaceable attachment to the housing. 
     
     
         11 . The cosmetic device of  claim 10 , wherein the second exchangeable drum assembly differs from the first exchangeable drum assembly in at least one of abrasiveness and compressibility. 
     
     
         12 . A drum assembly configured for rotatable use with a cosmetic device, the drum assembly comprising:
 an abrasive outer surface; and   a deformable portion disposed below the abrasive outer surface;   wherein the abrasive outer surface is rotatable by the cosmetic device to smooth and/or polish an outer layer of a nail of a user.   
     
     
         13 . The drum assembly of  claim 12 , wherein the abrasive outer surface includes one of a sheet of abrasive material and a coating of abrasive material. 
     
     
         14 . The drum assembly of  claim 12 , further comprising a generally cylindrical drum, the drum including the abrasive outer surface and the deformable portion. 
     
     
         15 . The drum assembly of  claim 14 , wherein the drum defines an aperture configured to receive a drive shaft. 
     
     
         16 . The drum assembly of  claim 15 , wherein the aperture has a cross-sectional shape that corresponds to the cross-sectional shape of the drive shaft. 
     
     
         17 . The drum assembly of  claim 16 , wherein the aperture is triangular. 
     
     
         18 . The drum assembly of  claim 12 , wherein the deformable portion is configured such that the abrasive outer surface and the deformable portion deform upon application of pressure during use of the drum assembly on a nail of a user. 
     
     
         19 . The drum assembly of  claim 12 , wherein the deformable portion includes a first portion having a first hardness and a second portion having a second hardness different from the first portion. 
     
     
         20 . An adapter assembly for a cosmetic device, comprising:
 an adapter body configured to be received within the cosmetic device;   a first end configured to engage a first drive member of the cosmetic device; and   a second drive member configured to engage a drum assembly;   wherein rotation of the first drive member of the cosmetic device causes a corresponding rotation of the second drive member and the drum assembly.   
     
     
         21 . The adapter assembly of  claim 20 , wherein the adapter body is a generally cylindrical member and includes an inner portion configured to rotate with the first drive member and an outer portion configured to remain stationary during rotation of the first drive member. 
     
     
         22 . The adapter assembly of  claim 20 , further comprising the drum assembly, wherein the drum assembly includes a drum member slidably received on a shaft. 
     
     
         23 . The adapter assembly of  claim 22 , wherein the shaft is shaped to prevent relative rotation between the drum member and the shaft. 
     
     
         24 . The adapter assembly of  claim 23 , wherein the shaft is triangular. 
     
     
         25 . A cosmetic device, comprising:
 an axially extending body defining an outer periphery in a circumferential direction and having:
 a first end; 
 a second end axially opposite the first end; and 
 a first portion between the first end and the second end, the first portion defining a first receptacle configured to receive a battery; and 
   a shell removably coupled to the body, the shell having at least one sidewall extending around the outer periphery of the body to at least partially define a cavity configured to receive the body and extending axially from the first end to substantially beyond the first portion.
