It's hard to believe that a product can be ruined so easily. After filling it with tiny needles, I wondered why my knees were covered in needles. The corner of the bag was missing. So I pulled out another bag and it was also missing a corner so whatever I put in came out. I didn't go through all the bags to see how many corners were missing. I don't need all 100 packages. little problem. Just a little annoying.
