What are those shelves called that you can hang in corners without any nails?

Hi,





I'm looking for the name of those white corner shelves that you can put in any corner of a room with no nails, I believe you twist something on the bottom and it locks in place in the corner.





Also, where I could buy them in the Greater Toronto Area or online.





Thank you in advance!What are those shelves called that you can hang in corners without any nails?
home depot has them.they come in white or maple.you get two brackets with them and they just slide on the brackets and lock into place. home depot in winnipeg has them so you shouldnt have any problem finding them in T.O.
