in 2000, when the parent company Energizer Holdings, Inc. was created. Within three short years they ventured into personal care products by acquiring Schick® Wilkinson Sword® razors.
So to say they make same Razor cartridges for Quattro and Wilkinson brand.
If you buy Schick Quattro cartridge, Quattro is printed on the plastic holder.
If you buy Wilkinson brand ,plastic holder Quattro is not printed but both are the same blades.
so you will not get quattro print on the cartridges you get (See the last picture)
you can verify this info by visiting their web site
please do not confuse and if you need the products that holder printed Quattro Please do not buy this product
