Cockatiels toys setup

[Hamdiayadi]

Hello , I have two cocktiels one male and one female, I couldn't setup some toys before because my country doesn't have , now I travelled to France and plan to bring many toys , useful perches , food plates , stands ect ... Anything that can make them enjoy , any recommendations please on what to buy ? I need to make sure the toys I buy are safe and they don't end up hurting them , and need suggestions in some of the stands that could be setup outside , thank you !
