How to care
1.Wipe, remove the dust, keep clean and dry
Keep your bird feeder hooks from salt / sweat / sea water / sea breeze / soil, for they have Chloride ion, it will let the stainless steel quickly rust if long-term touch. In general, stainless steel does not rust, unless you use improper.
I wanted to have two of these to use instead of purchasing the overly expensive window blind pole hooks (it took me more than a day to discover the term for that pole with a hook that you use when you are too short to reach the window blinds to pull them down). These give me the few extra inches I need to get those blinds down when I or someone taller has put them out of my reach. They fit securely into the holes in the handles and work perfectly at a fraction of the cost, plus it's easy to store them out of sight in a drawer when not needed.
These are great bird feeder hooks - I just wish I'd seen them sooner. I have several other hooks but the ends have a much smaller crook and often don't fit over larger branches. These hooks are really nice and large enough on the big end to hook over the sturdier branches that my heavier bird feeders need. I highly recommend them.
