Mice in a boxing bag is a little far fetched don't you think? I would inspect the bad to make sure that there is no rips of cuts or anything like that. If you buying online then read description carefully to find out the condition of the bag.
Dude, Ebay has a grip load of punching bags for sale. Some even $30 brand new 100lbs. Some comes with 2 pairs of boxing gloves. They look like good enough of quality to me.
Depends if your buying it on Amazon.Ebay,Overstock.... and the Boxing Bag looks overly dated then leave it alone
But if your buying it on an ad where you can inspect the Boxing Bag and its in good shape then go ahead and get it .
for some reason I am a little paranoid that it might have mice or something stuffed in it. the reason I want a used boxing bag is it saves me about $100. than buying new, what do you guys think? am I just too paranoid?
