Craft Foam Half Balls

A flat bottom keeps this half sphere steady on work tables, making it a reliable base for floral toppers and classroom models. High density polystyrene holds pins, picks, and craft glue without crumbling. Use it as a foundation for school science projects or wrapped party decorations.

Dense white foam

High density polystyrene holds its shape under wet paint, craft glue, and pressed pins. The surface takes fabric wrapping, pinned sequins, rhinestones, yarn, and paper without tearing or shedding coarse debris across your work area.

Flat base design

The molded flat bottom rests firmly on tables and pedestals without rolling. It provides a level foundation for mini centerpieces, cake pop displays, floral arrangements, and half round wreath bases that need to sit flush.

Classroom model base

The smooth dome works well for school science displays, geological cross sections, and solar system models. Students can map out landforms, paint terrain layers, or pin markers directly into the core for clear presentations.

Clean cutting core

Serrated craft blades slice through the foam cleanly when you need custom angles or recessed pockets. The core stays firm around inserted dowels and stem picks, keeping floral stems and decorative toppers right where you place them.
