I use these storage containers for under the bed storage. They are great with having wheels and I don’t think I have paid full price for these.
My husband uses these to store his model rail set in as well. The size is perfect for the tracks.

These 30 Lt tubs fit perfectly under most beds. I have bought several of them and haven’t had an issue with them. They are frequently half price at Woolworths making them fantastic value for money. My eldest daughter used these for all her shoes and has them stacked in the bottom of her wardrobe as well as under her bed for all her other storage needs.
