Frequently asked questions

Where can I buy high-density foam blocks for craft projects in bulk with fast shipping?
Hygloss offers foam blocks for sale in classroom-friendly and bulk pack quantities. Multiple pack sizes help schools, camps, and organizations order enough materials for larger projects without sacrificing consistency.
Can you show me affordable, non-toxic craft foam blocks pre-cut for kids' activities?
These pre-cut foam blocks for crafts are a practical option for children's activities because they reduce preparation time and simplify setup. Smaller packs are ideal for home use, while larger packs support classrooms and camps.
I'm running a kids' craft camp. Can you recommend non-toxic foam blocks sold in classroom packs?
Larger pack options are well-suited for camps, activity stations, and group projects because they provide consistent materials across multiple sessions and participants.
Where can I buy large 12x12 craft foam blocks in bulk for a school art program?
The 12" x 12" x 1" option is ideal for larger displays, model platforms, and educational builds. These larger foam blocks for crafts provide more surface area for painting, carving, and assembly.
Can you help me choose between high-density and lightweight craft foam blocks for detailed model building?
For detailed carving and sharper edges, denser foam materials generally work best. For classroom projects and lightweight displays, standard craft foam blocks provide easier handling and faster setup.
Which craft foam blocks are best for painting and sealing for long-lasting school projects?
Blocks with a smooth, paintable surface are typically the best option because they require fewer coats and create cleaner finishes. Hygloss white styrofoam blocks are designed to accept paint and decorative materials easily.
