Big thank you to everyone who posted here. We had a great send off for my friend the other night and in the end I went a bit extreme with my gifts for her.
A short list of what I got her is,
A Sailor Moon t-shirt, bag, key ring and pop vinyl (She's obsessed with it)
Toys for her young sisters
hand written cards that I had translated into her native language for her and her family (Left 20 euro inside the card for her sisters)
and a bunch of pictures framed together showing her with a bunch of different friends she's made while studying here.
Big thank you to everyone who commented here, though I am very grateful for the advice my wallet wasn't ^_^
