I bought these puzzles as a gift for my five-year-old daughter, who loves Hello Kitty... I was glad I did ! These jigsaws are durable, not too small and great value. It kept her quiet for hours and she still uses them, I would highly recommend them for your own little princesses but I do think that 5 is the minimum age, any younger and I feel the pieces would be a bit small. However, as something for the little ones to complete with Mummy or Daddy, maybe 4 years ? Either way these are very well made and make a great gift for HK fans young or old alike :)
