DECOHS4 PCS Pick Apart Foam Insert- 2 Size Pick and Pluck Foam- Pluck Pre Cube Sheet Foams with Bottom Use for Board Game Box Cases Storage Drawer (Length 12 Inch)

I used this to put in a soft shell case for my telescope eye pieces and some other lenses. I'm not really a fan of the pluck and pull unless you happen to have square objects. But this worked out good enough for my needs.It comes vacuum packed and is ridiculously mishaped 😂. It will eventually return to normal size. I measured it 2 days later and it was right on with specs.

Quand j'ai reçu la mousse elle était vraiment compressé. Je l'ai mis dans la sécheuse à cycle délicat 5 min et voilà, la mousse était super belle et avait retrouvé l'aspect désiré

It does what you want it to do, but it is not a stiff foam. Quite soft and doesn't secure my heavy stuff well enough for my taste, but it works anyway.

When first received, the package is a air-evacuated unit, which made me think what did they send me. Upon opening the package, the foam pads inflate to their advertised size. One can pluck the small foam cubies out of the main unit to custom fit your needs. The two smaller pads do not have he cubies and one could either place them underneath the item you are storing.

Perfect for the purpose
