At present, I do not make these to withstand the elements, so no. Eventually they will rust (as all metals will do) if exposed to rainwater for an extended period of time. I have explored clear coating and such, but most products dull the shine of the metal and the glass.

They are all meant to handle a vibrant breeze.

How big do you want them?! I will have measurements posted shortly on every mobile, with a height, and radius of reach (x2 for necessary diameter.) I can make them as large as a space will allow, and can cover a ceiling with slowly orbiting mobiles in an array. I also make small desktop-type ones too.

Will they fit your space? Measure from the ceiling to the top of your reach with a measuring tape. If my listed height is less, you’re good to go. Check the diameter too: measure across the width of your space and make sure my mobiles aren’t bumping your walls.

No. not even in a constant breeze, or mounted on a mechanical spinner. I guess if you use a shoddy hook or crappy string, that is a possibility.

They are built to not tangle and the glass circles will not “hit” into each other. If one of the steel wires does happen to cross over another and overlap, it most likely will revert to it’s intended form with the next breeze.

You can play with them too.

They are not good at soccer, but have survived the brunt of a few errant kicks. I have a son.

Usually my mobiles can be (gently) collapsed closer together, and I use rubber coated garden wire to gently hold them firmly in place. They can be tied so they don’t move much, and when you untie them at home, they should gently cascade open. If you are buying one on site at a gallery, and I am nearby, I’ll be happy to get it ready for you. If you live nearby, I may be available to hang it for you too… you might need to supply the ladder!

Carefully! Gently tied in a couple places with rubber coated wire to keep them from rattling about, then nested in a box with lots of bubble wrap. You should be able to just untwist the rubber ties and it will be ready to hang up!

Typically I need to clean anything that can gather dust around the house, so yes, every once in a while. Window cleaner works just fine.
