Living in cali this is kind of important. It works perfectly well for my ever evolving exhibition setups. Perfect for larger pictures and even small decorative shelves.

No matter how hard i pushed or wiggled them together, they come right apart. Does not stick. Adhesive hold is subpar.

It’s basically velcro. They adhere great, but if you apply to painted walls(sheet rock underneath) the chances of them ripping off paint is high. The velcro is so strong that when you need to remove the picture it completely pulls off paint.
