Someone kindly supplied me with this neck pillow but it was a little bit saggy. Then, someone shared some of styrofoam beans from a broken bin bags. It was a bit tricky as the styrofoam are highly static and I did not have a funnel then either. When the necessary materials are now completed, I have just now been able to refill and this neck pillow has a renewed firmness. Thank you again for sharing me your neck pillow and beads!
