All of our stickers are packaged 300/box unless noted.  Each sticker is prepackaged in industry standard cardboard sleeves (4-1/2" long x 3" wide) ready to vend through standard industry sticker machines.  Each box of 300 stickers will generally fill a single column of a sticker machine.  For example, a 2-column sticker machine would require 2 boxes of stickers, one for each column. S/h is $10.00 per box within continental U.S.
