Ps thats a sexy rack Id say they r a bit small aswell. Im thinking about 9L bins from reallyusefullboxes. If ur in the states ur luckier then me you can order direct from the supplier. Or if ur canadian like me staples carries them and usually has 12 on hand they cost about 11 bucks. They are super sturdy, ive jumped on them im 230, they have latching & locking lids too. Tehy cost a bit more but they are thick walled, clear and reinforced bins. I use 17L for juvies, 9L for my baby rack in build right now, and 32Ls for full growns housing tubs.
