My sister recently suffered a mild stroke which left her with left side weakness to her leg, arm, and hand. Her handwriting was negatively impacted due to the weakness. Her therapist suggested using pop beads to therapeutically strengthen her hand. She could not find them anywhere in Wichita, but I found them on Amazon and had them delivered to her. They worked like a charm. She had a lot of fun working with them as well as experiencing fond memories of our youth when we got them as  children when they were first introduced. Her handwriting is as beautiful as ever. Thanks for a great product and the rapid delivery!
