I got Hermione's wand fomr NOble al while ago and was about to break but i can see a metal rod inside it so maybe noble puts a metel rod in some of theirs becauce I got Harry's wand at the same time and it snapped clean in half (Igot a new mattris for christmas and when i was helping my dad bring it in, I put the mattris on top of it

) Anyway Harry's didnt have a rod???
Basically my question is that are the japenese better??? If so where can i get them

Thanks for your help!!
P.S I got Sirius's wand for Christmas and it's really cool.
