1 . A case for a substance that is applied by an applicator tool, comprising:
 a housing comprising a mechanical connection and an opening on a first end, the opening adapted to receive an exchangeable cartridge having a cavity for use in containing a substance; and   a handle configured to removably attach directly to the mechanical connection of the housing and comprising a connecting device adapted to removably attach to an exchangeable applicator tool with an applicator end for use in applying the substance.   
     
     
         2 . The case of  claim 1 , further comprising the exchangeable applicator tool having an applicator end, wherein the applicator end of the exchangeable applicator tool is inserted into the cavity of the exchangeable cartridge when the case is in a closed position. 
     
     
         3 . The case of  claim 1 , wherein the housing comprises a window for viewing the cavity of the exchangeable cartridge. 
     
     
         4 . The case of  claim 1 , further comprising the exchangeable cartridge, wherein a defining upper edge of the exchangeable cartridge is flush with a defining upper edge of the housing when the exchangeable cartridge is removably connected to the housing. 
     
     
         5 . The case of  claim 2 , wherein the applicator end of the exchangeable applicator tool is selected from the group consisting of a brush, a comb, a pad, a cotton swab and a sponge. 
     
     
         6 . The applicator end of the exchangeable applicator tool of  claim 5 , wherein the brush is selected from the group consisting of a straight brush, a curved brush, an angled brush, and a brush of larger diameter at a first end of the brush than at a second end of the brush. 
     
     
         7 . The case of  claim 4 , wherein the exchangeable cartridge is recyclable. 
     
     
         8 . The case of  claim 2 , wherein the exchangeable applicator tool is recyclable. 
     
     
         9 . The case of  claim 2 , wherein the exchangeable applicator tool is washable. 
     
     
         10 . The case of  claim 1  further comprising a skirt. 
     
     
         11 . The case of  claim 2 , further comprising a removable cover for the exchangeable cartridge. 
     
     
         12 . A method of using a case for a substance, comprising:
 providing a case comprising:
 a housing comprising a mechanical connection and an opening on a first end, the opening adapted to receive an exchangeable cartridge having a cavity for use in containing a substance; 
 a handle configured to removably attach directly to the mechanical connection of the housing and comprising a connecting device adapted to removably attach to an exchangeable applicator tool with an applicator end for use in applying the substance; 
 an exchangeable cartridge removably attached to the housing; and 
 an exchangeable applicator tool removably attached to the handle; 
   removing the exchangeable cartridge from the housing; and   removably attaching a second exchangeable cartridge to the housing.   
     
     
         13 . The method of  claim 12 , wherein the removably attaching is accomplished by a mechanical connector. 
     
     
         14 . The method of  claim 13 , wherein the mechanical connector is selected from the group consisting of a screw connector, a snap, a twist-lock connector, and a snap-lock connector. 
     
     
         15 . A method of replacing an exchangeable applicator tool in a case for a substance, comprising:
 providing a case comprising:
 a housing comprising a mechanical connection and an opening on a first end, the opening adapted to receive an exchangeable cartridge having a cavity for use in containing a substance; 
 a handle configured to removably attach directly to the mechanical connection of the housing and comprising a connecting device adapted to removably attach to an exchangeable applicator tool with an applicator end for use in applying the substance; 
 an exchangeable cartridge removably attached to the housing; and 
 an exchangeable applicator tool removably attached to the handle; 
   removing the exchangeable applicator tool from the handle; and   removably attaching a second exchangeable applicator tool to the handle.   
     
     
         16 . The method of  claim 15 , wherein the removably attaching is accomplished by a mechanical connector. 
     
     
         17 . The method of  claim 16 , wherein the mechanical connector is selected from the group consisting of a screw connector, a snap, a twist-lock connector, and a snap-lock connector.
