Not sure whether this is the right place to post this query, but anyways I will see

I wonder if anyone could tell me of the implications to use a tax-free item in Finland, bought from Finland besides losing the refund?
I, perhaps, unwittingly bought some jewelery for a friend who is coming over from Russia and have it gift-wrapped. Since I won't be the one who will take it out ofFinland, I want to remove the seal they place on such packaging before presenting it to her. I understand that I will lose the tax refund for this, but is there any other flip-side or legal complexity to this? Any aftermath?
Any help on this subject would be greatly appreciated.
Ter,
