These Wilk's are made at Gillette's super modern factory in India for the sub-continent & Asian markets.
These 5 packs are 4 + 1: 4 indian wilkinson swords + 1 gillette super platinum (my personal favorite blade of them all)
You get 20 x 5 pk's, so that's getting the equivalent of 16 packs of Wilkinsons + 4 packs of the Gillette super platinums which are expensive blades.
100 Wilkinsons for only $10.00, you can't beat that... if you can let me know, please ! The 4 pks of Gillettes mixed in are worth the 10 buxs alone
