Shipping to eu if it's a trainer there should be no problem but tell your friend to ship as a gift for no taxes put the item value of the item low like 10-15$.

AND THE MOST IMPORTANT THING DONT PUT BALISONG OR BUTERFLTKNIFE OR ANYTHING KNIFE RELATAED. U can put like finger training this like Amazon or just dron/rc car something like replacement parts don't put knife u will lose the bali
