The PLY wall element is made of new, ultra thin birch plywood, almost see-through. The thickness of the material is 0,45 mm. This textile-like, thin plywood is attached to a solid wood frame, which again can be fixed to straight surfaces by stickers, velcro, picture hooks or screws. There are two different models of PLY, a curvy one called PLY1 and a gentle wave called PLY2. Both models come in two versions, mirror images of each other, so that the waves continue: PLY1A/PLY1B and PLY2A/PLY2B.
