I don't think he means the tube kind they come in a 1 oz bottle there are several different colors too violet,blue, green, red ,green orange and a few more I myself have been using these for awhile now and you really get some wicked effects in some cases almost like having a color shift when done over certain colors its a bit pricey but you really only need a drop or two thinned out to do a bass size lure i get mine at ac moore close to 8 bucks a shot
