Are these certified safe for children? what type of plastic are these made of? do they contain phthalates or pvc?

They are clear plastic tubes. I don’t know about being certified. I don’t know what they’re made of but they are awesome! Highly recommended!!! I used them to distinguish sounds high, low; sound or no sound, etc. I used them with all ages of preschool children.

is this a sensory kits or are they pre assembled?

they're just empty tubes. nothing in them at all. you have to decide what to put into them for them to actually have the "sensory" aspect.

Will they hold water?
