About10 + years ago ,childrens toys were manufactured as battery operated and children were swallowing the batteries apparently.
So they started the safety screw to open them … Tiny screws and so easy to slip out of hand and lose and No replacement.
I eventually refused to buy any toy that required a battery .
I guess I won’t be buying the MB + … and then spending more money to get a better tiny screwdriver delivered by Amazon
All made with plastic in a World that can not have free shampoo in a small plastic bottle anymore. Because we all want to be Green .
