Ooh this looks fun! My kids love those expanding tree toys, very satisfying to watch and really keeps them occupied, plus they're learning about how things grow which is perfect for that age la. RM5-12 is such a steal for something educational, and the different patterns (the sakura especially cuteee) means each child can pick their favourite. The STEM angle is legit too since they're seeing cause-and-effect happen right in their hands, not just staring at a screen. A few of us mums have grabbed these for goodie bags and birthday gifts recently sebab durable and the kids actually go back to them again and again!
