Using these Schylling Nee Doh Teenie Squeeze Hearts is super easy. Just grab one and start squeezing! It's a fun way to relieve stress or play around. They're great for kids aged 3 and up to enjoy on Valentine's Day or any day. When it comes to care, keep them away from sharp objects that could puncture them. If they get dirty, you can gently wipe them with a damp cloth. Since the styles are assorted and randomly selected at dispatch, if you have a specific style in mind, remember to leave a note in your order. And don't forget, each item is sold separately. If you want to see all the styles in person, head to your local Toyworld store.
