Seems like good putty
My only complaint is that the instructions I received with it are all in Spanish. You shouldn't sell products in this country that don't have English instructions.

Quake Hold is amazing!!!
I needed something to anchor a small antique vase to a stand, that wouldn't harm the vase. The people at Scott Laurent Gallery in Orlando suggested museum putty. I couldn't find any locally so I ordered Quake Hold from Amazon. It works great! Once applied (with no waiting period), objects hold tight, but can be removed with a clock-wise twist, and the putty comes right off of the surfaces. We have four active cats, and I trust this stuff enough to display two very large vases which I've anchored to end tables. They haven't budged -- the vases, not the cats. They're everywhere. A little goes a long way too. I ordered four packages and I just finished the first, having also used it to attach fabric to some art glass for display. It's cheap, clean, and does the job. What else could you want? SM

Did not work as expected
I had been told that this was one of the best products for holding objects in place but it has not worked at all for me. It did not stick to the glass object I wanted held down, nor did it stick to the shelf. I tried another item after working the putty well and it too did not stick. I wonder if this was a bad batch or perhaps had been on the shelf too long. I am awaiting instructions for returning it.

Cats and glass
I have a collection of glass figurines. I also have a collection of felines. Without museum putty, I couldn't have both!

Quakehold!~ Museum Putty
This is a great product. I bought it for the pictures in our office so they will stay straight on the wall. Once there it does not come off until you take it off. You don't even see it. People just think you are great at hanging pictures. And I like that!
