I've used Collonil nano pro with no issues on all leathers such as Chanel caviar, calf skin, goat skin, washed lamb (chain around maxi) - also Hermes box calf, Togo. Not tried it on the classic lamb yet as I don't own any lamb currently. But I guess it should be fine - after the mandatory spot test first on all bags, regardless of previous success with that type of leather.
Not tried carbon pro.
