I have to agree... metal or even wood. I had one of those cheap Chinese plastic "parts organizers" for small screws etc ( I know, much smaller drawers than you are thinking about) sitting near a window. After 2 yrs the plastic starting getting brittle and the drawers break apart when you pull them out too fast. My metal bolt bin will outlast me, as will the wooden one my daughter and I made when she was in Grade 12. She's in her 30's with 2 kids now. Go with things that last and you won't regret it later.
