Would you suggest me what kind of gift

Since both have different nationalities and languages, you better send him a book on photography, full of lovely pictures.

What I would do is find out where they like to shop and see if you can get them a gift certificate online and send it to them. I always felt that if you dont know something specific to get a gift certificate always works.

It really depends what kind of things he likes.. flowers and chocolate.. something for his car.. apparel.. books.. jewellery. Dont forget to express yourself with a card! Just think of something that would truly astonish him.

maybe you can give him a thing that is from your country that he never seen in his country..a thing that is nice and maybe that is useful so that he can always think of you..i already had in that situation, my ex was from Canada and from the Philippines..last January i send him a gift, it's a pendant and it has a pic of me and my daughter, it's really touches his heart and makes him cry..

Why don't you sne him something special from your country. Something that outside of your contry would be considered a delicacy or expensive import. Like Swiss Chocolate from Switzerland. Or Maple Syrup from Canada. Whatever is the specialty of Sweden, send him that.
