USA, Canada / Relatives from Poland are coming to visit us in the USA. What do we buy for them? [7]

We have some guests coming for a visit from Poland. They are long lost realitves. We want to buy some gifts for them to take home as souviners for themselves and other family members that didn't make the trip. Any suggestions? What's hot in Poland right now? Our guests are 60 years old and 15 years old. Other gifts should be for all the family members.
