The little sponge balls grip the wood without slipping, and the moss stays put once you tuck it in. I've watched the plants look fuller on my tree setup every day since adding these, which makes the whole aquascape feel way more natural.

Wrapped these around my driftwood bonsai branches in about ten minutes and the moss already looks like it's growing naturally from the tree. The sponge base holds its shape without crumbling in the water, which was my biggest worry. My tank's centerpiece finally looks like a proper miniature tree in

Wrapping moss around these sponge spheres took a bit of patience at first, but once tucked into the driftwood bonsai the foliage looks way more natural than bare wood. They're squishy enough to pin down without crumbling, though a couple arrived slightly dented.
