Anyone know where can I buy puku walker in shop?

I think they sell it at any Spring Maternity outlet. Have seen Puku items there before. Maybe you can check it out? Spring Maternity has outlets in JEM and VivoCity.

Kiddy palace sells it too.. I think they are also having store wide discount this month

Can buy online from Lazada or from here https://mummysmarket.com.sg/deal/puku-baby-walker

You can get them at NTUC Extra (where there is baby section like Amk NUTC Extra) and OG.

Kiddy palace or NTUC extras . If not you can also get it online at carousel
