It is NOT at all Leak proof!!
Do not put any liquid in and shake it, you will get it every where.  So bummed I bought this product.  If all you need to do with it is set in on a counter with water than fine, but as soon as you pick it or move it, it leaks out from all sides no matter how hard you try and keep it closed.  Do not travel with any liquid it just pours out.
