Each pack includes 100 clear, flat, self-sealing cellophane bags measuring 2 1/4"x4 1/4".  These babies fit perfectly in candy bar slots.  I use these bags in a lot of my packaging.  I buy them from clearbags.com in bulk, then pass most of the discount and pass most of the discount on to you.  I have to sell these in 3-pack minimums or I lose $ on shipping.
