Using these Schylling Chonky Cheeks Hamsters is easy. Just give them a gentle squeeze and watch their cheeks puff up. They're great for kids aged 3 and up to play with and enjoy. When it comes to maintenance, keep them away from sharp objects to avoid tearing the squishy material. If they get dirty, you can gently wipe them with a damp cloth. Remember, the styles are randomly selected at dispatch, so if you have a color preference, add a note in your order. Each hamster is sold separately, so you can collect them all.
