These are good quality and graphically attractive thoughfully-created puzzle. I got four of these for my just 3 year old son because I understand his competency. I got it mainly with the intention that he will develop multiple skills including fine motor, hand-eye coordination, patience, persistence, problem-solving, sequencing, etc, while enjoying the satisfaction of accomplishing the challenge. With little guidance and help, my son accomplished the 35 piece puzzle whereas he did the 24 piece puzzle mostly on his own. Gradually he got good at solving the 35 piece puzzle too. These puzzles have good replay value. Good combination of fun with skill development. Also, most importantly made in the country dearest to me 🇮🇳
