After repairing over 8000 -8" M A dolls I came up with the best way I figured to fix them. The bands are from a heavy duty rubber I have used them on 8",10",& 12" dolls .I am including enough bands to repair 12 dolls. It only takes a band puller and a pair of pliers-I also sell complete sets with bands,Tools and Instructions on Ebay-go to my store. I have found that after 15 years the elastic bands become brittle and break down. I re-string all the older dolls I sell so you won't have any problems-I have lots of MA dolls on my Ebay store.These bands will not work on walkers
