Spent an embarrassing amount of time looking at hooks online before happening upon these. Love the unique, minimal style. Good function based on one month use - slide easily on the rod (just rub some wax paper along first) and haven’t noticed any rusting even in my humid old bathroom.
Functional and much more aesthetically interesting than standard shower curtain hooks. Also feel great about avoiding plastic. Got the black and they look really sharp. Lived with them a couple weeks now and they work just as well if not better than any other shower hooks I've ever had.
