Since he is a trendy guy, you must give him some special gifts, preferably something personalized that is not available on the market.
I recommend giving him a tungsten steel personalized military badge. I don't know if you have watched the Korean drama "City Hunter". The military badges in it are very popular now. Military badges are a symbol of bravery and conquest, and this is exactly what society requires of men now. They can be customized online. You just need to send your buddy's name, date, and city, and they will be engraved on the military badge one by one. PS: It is recommended to use the English version, which looks very handsome. It is also recommended to choose a black imported leather rope, which is of good quality and unconventional. Accessories with different materials are a very popular trend this year.
I believe that when a trendy guy sees this gift, he will shout "Wow, it's really trendy." Your friend will definitely like it.
