Where is the best website to buy counterweights and dont offer me any not looking for trades thnx 
I don’t know if there is a place that just sells counterweights - as far as I know… You can always make your own by putting a slip knot over a dice or ball or something… I do have some, that I don’t use…
Try places like amazon, or maybe this site, I’m from the Uk so I use amazon or euro-yo.com!
DONT!!! just put the slipknot over a die or ball… it will fling off and slay your baby kitten… Drill a hole in somthing… (With adult supervision) or I broke open a bouncy ball and used a razor blade to put a little V shaped gap in the centor and glued it back together… its hard to explain but it works…
REMEMBER!!! ALWAYS HAVE ADULT SUPERVISION WHEN HANDLEING SHARP OBJECTS OR POWER TOOLS!! Unless your like 30…
just go to duncan yoyos website which is i think yo-yo.com and they got some good deals
