TenTens only Ninjutsu

Name:Reappering and disappearing Iteam

Effect: when Tenten throws a item she can make it reapper as 1000 or more version so if she throws a kuni and she uses the jutsu it will make the kuni turn into 1000 kuni and she can also make iteams dissapear

So, it's like genjutsu right? Or is it Ninja Tool Summonig that makes it work?

Its ninjutsu because it copies a item or it makes a item disappear
