Yes, Those Atalaya ones were what I had looked at. I have never used them so no idea on quality.

I purchased about 100 sets of Atalaya generic decal sheets and Policar Monoposto decal sheets a couple of months back for resale.
I only knew of the company vaguely from forums until then, but wanted to make F1 decal sets available to sell alongside the cars.
This is a public facebook group created by ScaleAuto who are Slot.it/Policar distributors for Spain, and resellers of Atalaya decals through their retail store CricCrac.

But you can also deal direct with Atalaya through their own website.
Everyone who has used the Atalaya decals in NZ is very happy with the quality.
I have seen a couple of monoposto cars finished "in the flesh" and they looked absolutely spanking.
