Sturm Panzer Blade attack response size?

Hi guys! i have a sturm panzer Schneider and i have found out that for some reason whenever i change the response with silicon it falls off in about a day…I had an extra pair of the response the yoyo came with and they lasted forever…I was just wondering what size the response was and what response i can use instead (if there are any) i just dont want to have to pay for all the shipping to get the response from rewind. ;D Thanks guys

I would try emailing them directly. I’ve bought multiple throws from them and they’ve never charged me shipping. If u buy a few sets they might ship them for free. Plus everything is cheaper than that other store
