Stretchy noodles are as described, but I was hoping they would be thicker. Expect thin. Kids love them though. They are stretchy and fun to fidget with. A great sensory toy for ages 1 through 4. My one year old does chew them and they don't break.
My kid adores stretchy noodles. He uses them in create, calm, and seek sensory input. We've had them for months and they have endured a lot of stretching and chewing with zero damage.
