These are great!  We are using them instead of towel racks in the bathroom, and they work wonders.  My husband only uses 2 hooks, so the middle one can stay closed.  I use all three hooks.  I love that I can hang a bath sheet (larger than a bath towel), a hair towel, and a washcloth in such a small space.  And each item can dry appropriately, rather than layering wet washcloths on top of damp towels.  Great idea!

Of course, they would also work great for their intended use, hanging coats!
