         4 . The applicator tip ( 30 ) of  claim 1 , wherein a portion of the plurality of internal ridges ( 32 ) are substantially straight. 
     
     
         5 . The applicator tip ( 30 ) of  claim 1 , wherein a portion of the plurality of internal ridges ( 32 ) are curved. 
     
     
         6 . The applicator tip ( 30 ) of  claim 1 , wherein a first portion of the plurality of internal ridges ( 32 ) are substantially straight and a second portion of the plurality of internal ridges ( 32 ) are curved. 
     
     
         7 . The applicator tip ( 30 ) of  claim 1 , wherein the plurality of internal ridges ( 32 ) comprises from 2 to about 20 internal ridges. 
     
     
         8 . The applicator tip ( 30 ) of  claim 1 , wherein the at least one external ridge ( 31 ) comprises a plateau. 
     
     
         9 . The applicator tip ( 30 ) of  claim 1 , wherein the applicator tip ( 30 ) is made from an elastomer. 
     
     
         10 . The applicator tip ( 30 ) of  claim 9 , wherein the elastomer is a thermoplastic elastomer, a styrenic, a copolyester, a polyurethane, a polyamide, a polyolefin blend, a polyolefin alloy, a reactor TPO, a polyolefin plastomer, a polyolefin elastomer, and/or combinations thereof. 
     
     
         11 . An applicator ( 10 ) comprising:
 (a) an applicator tip ( 30 ), the applicator tip ( 30 ) comprising:
 (i) at least one external ridge ( 31 ); 
 (ii) a plurality of internal ridges ( 32 ); and 
 (iii) a plurality of internal channels ( 33 ) between the plurality of internal ridges ( 32 ); and 
   (b) an applicator handle ( 20 ),   wherein at least a portion of a perimeter of the applicator tip ( 30 ) is free from the at least one external ridge ( 31 ).   
     
     
         12 . The applicator ( 10 ) of  claim 11 , wherein the applicator tip ( 30 ) has a durometer rating of from about 45 A to about 75 A. 
     
     
         13 . The applicator ( 10 ) of  claim 11 , wherein the application tip ( 30 ) is colored 
     
     
         14 . The applicator ( 10 ) of  claim 11 , wherein a portion of the plurality of internal ridges ( 32 ) are substantially straight. 
     
     
         15 . The applicator ( 10 ) of  claim 11 , wherein a portion of the plurality of internal ridges ( 32 ) are curved. 
     
     
         16 . The applicator ( 10 ) of  claim 11 , wherein a first portion of the plurality of internal ridges ( 32 ) are substantially straight and a second portion of the plurality of internal ridges ( 32 ) are curved. 
     
     
         17 . The applicator ( 10 ) of  claim 11 , wherein the plurality of internal ridges ( 32 ) comprises from 2 to about 20 internal ridges. 
     
     
         18 . The applicator ( 10 ) of  claim 1 , wherein the at least one external ridge ( 32 ) comprises a plateau. 
     
     
         19 . The applicator ( 10 ) of  claim 11 , wherein the applicator ( 30 ) is made from an elastomer. 
     
     
         20 . The applicator ( 10 ) of  claim 19 , wherein the elastomer is a thermoplastic elastomer, a styrenic, a copolyester, a polyurethane, a polyamide, a polyolefin blend, a polyolefin alloy, a reactor TPO, a polyolefin plastomer, a polyolefin elastomer, and/or combinations thereof.
