Uneven materials, fragile surfaces, and excessive prep work can slow down even the simplest craft build. Hygloss craft styrofoam blocks provide a ready-to-use solution for classrooms, science projects, floral displays, and creative DIY work where a clean, sturdy base matters.
These lightweight foam blocks for crafts are easy to cut, carve, sculpt, paint, and decorate, making them ideal for students, teachers, crafters, and event planners. Available in multiple sizes and pack counts, they help projects move from idea to finished display with less trimming and preparation.
Whether you're building a science fair display, creating floral centerpieces, or designing decorative signage, Hygloss styrofoam blocks provide a reliable foundation for countless projects. Their lightweight construction makes them easy to handle while maintaining enough durability for carving, shaping, and decorating.

Available in both rectangular and square formats, these white styrofoam blocks can be painted, glued, layered, sealed, or sculpted to match your creative vision.
