Half Foam Ball 2-Pack - 7.8 x 7.8 x 3.9 in, White - DIY Art Craft & Modeling Supply - Sphere Dome for Crafts Projects

I add flowers to this to make it look like a nice bouquet and it works great

My twin boys did poster boards on a planet they picked. We used hot glue to glue the half circle to the board. It was easily painted to look like the planet and held up well. The sphere wasn't damaged in any way either.

Decent quality but overpriced for sure

Worked great for the 7th grade human cell. Still have other half for the next kiddo.

Definitely expensive for just one foam circle

It works for what we need it for.

Use these on all my can light installations through attics. Keeps it air tight and prevents bugs from slipping through the gaps from the attic (small attic spiders). Will not work with large can light housings but great for the retro fit kit installations where housings are not needed. Caulk or foam them down to the back of the drywall.

Cheap, not well made at all! You get very rough edges where the two halves come together. I can’t even get the halves to go together they’re so rough. On the outside you get two molding injection globs one on each half. I paid way too much for this crappy item! Do better Amazon, pick better sellers!
