Using the NeeDoh Mac 'N' Squeeze is easy. First, pop off the lid. Then, you can start pulling, squeezing, and smushing the neon noodles to enjoy the squishy feeling. When you're done, just put the lid back on to keep the noodles in the container for next time. As for maintenance, keep it away from sharp objects to avoid tearing the noodles. Don't expose it to extreme heat or cold as it might affect the texture. If it gets dirty, you can gently wipe it with a damp cloth. This toy is suitable for all ages, but always supervise young children to make sure they don't put small parts in their mouths.
