Thanks for your experience. I talked to BV before I put anything on my ball bag and they recommended to use "Collonil Nanospray" which is a very light spray and it's made for delicate leathers and other cloths like cashmere. I used this and nothing chnged the leather.
I had bad experience with Apple Garde spray and lotion in the past with my Balenciagas so therefor I was really careful and glad that I followed the advice as here they wouldn't take it back when you mess it up yourself.
You were really lucky that they exchanged it.
Tanja,
I bought a Collonil waterstop +UV protection spray at Mulberry store, do you think it is the same as Collonil Nanospray? I know you girls tried the spray on the lambskin veneta bag, how about Julie? It is deer skin.
Thanks.
