Extremely cheap and brittle plastic. Three sections were broken and cracked out of the box. Marketed as durable but this type of plastic is nearly the cheapest kind. If it does not arrive broken and if you are gentle with it with no tension or stress put on it, then it should work fine. This is what you should be able to find for $3 at the dollar store, not on sale for $10. Wayfair is sending a replacement free of charge which is appreciated.
