My sister and her family are coming to the UK for Christmas. I haven't seen them for 3 years so very excited. I have presents sorted for all of them apart from 15 year old niece. I don't want to give her vouchers as I send her money every year and this time I can see her opening something. But what? I don't know what her taste in clothes is (or her size!) so am ruling that out. Whatever I buy she's got to take back in her suitcase so that rules out anything too large or breakable. Budget is £30 - £40.
Any ideas?
