Ooh menarik ni! A few of us tried kinetic sand before and the kids memang suka main, therapeutic siot especially kalau they're fidgety or anxious, bagus gak for sensory play. The Sand ni seems like a good option since it won't dry out (so no need keep rewashing) and it's safe for kids 5+, plus the price is quite ok for 2kg lah especially with the flash sale. Just make sure supervised play je, and maybe set it up on a tray or mat so less messy around the house!
