I asked them to replace the zip tie on my Addy and sent her in to get the string and they told me that they do not have the strings. Maybe then they just use the existing string if it's still good. I ended up getting a string from a local doll hospital and it's different, but it still works for holding the head on and I can take it off if she ever needs any work. I also cut off a zip tie from another hospital doll I got back and it was quite difficult. I had to pull out the ol tool box. Good luck with you bitties.
