20x20x3 cm polystyrene blocks in a pack of 6, designed for crafts, decoration, modelling and themed displays. A useful format when you need clean, consistent pieces.
If you need a flexible format, the 20x20x3 cm polystyrene block in a pack of 6 is a useful option for crafts, decoration, modelling and themed displays. Its lightweight structure makes transport and handling easier, especially when several matching pieces are needed in the same project.
The material can be finished with paint, fabric, paper, glitter or EVA foam, and it can also be reshaped through cutting. That is why it is often used in craft work, school projects, window displays, models and visual props. It also responds well to nichrome wire cutting when more precise shaping is needed.
What makes this size attractive is that it is offers a format that works well for lightweight pieces, flat bases and layered layouts. For small and medium creative jobs, that gives a good balance between appearance and ease of use.
As a general guideline, the 20×20×3 cm format works well for decorative compositions and functional pieces where you want moderate volume without making the piece bulky.
