Anyone used these pillow while flying with toddlers? Where to get them in Singapore?

You can join this grouphunt deal. https://www.grouphunt.sg/posts/vQhRLwspxaM2pddia/1st-class-kids-seat It is $42 and delivery should be less than $6. I think the hunt is ending soon so got to place your order within the day if you want to get it at that price. Hope this help! :)
