Do you bring a lot of jewelry when you travel abroad? There shouldn't be too many declarations. It really depends on the number you bring. If it's too much, or if you just want to buy it, it may be a bit troublesome. In principle, there will be no restrictions on personal belongings carried abroad, but if they exceed a certain quantity or weight, they may be identified as smuggling. Since it's just an outbound tour, why do you bring so many?
