I asked once aaaages ago if it was possible to get sport/practice "weapons" at stores (like bamboo/wooden swords, etc) and the answer was yes! So I imagine bows with arrows that lack points/are tipped with something designed to NOT pierce flesh would probably fall under that category.

Since, y'know, archery as a competitive sport is very much a thing in the real world so why not hobbyists in pokeworld too?
