I honestly expected for this to be like styrofoam when I saw "Polystyrene," but these are closer to a PVC type material - like a lightweight hard plastic. They won't be snapping or breaking anytime soon! I am very happy with these. Excellent quality, all pieces included and all measured as advertised. The instructions give a lot of different layout options with these pieces, which is pretty cool. This is going to go on my TV wall, so I am using the pictured layout, as it is perfect to frame my 75" samsung tv, and the two side pieces are perfect to frame the two 24"x36" paintings I have for those spaces. This is really going to elevate the space and I don't have to do all of the footwork and mitering to DIY them. Well worth the price.

easy to assemble with clear instructions

I couldn’t be happier with this molding kit. It was lightweight, easy to cut and install, and transformed my plain walls into a custom-looking accent wall. Once painted, it looks like expensive trim work. Great quality and an affordable way to give any room a designer feel.

These wall molding panels were an easy and affordable way to create a custom, high-end look. The lightweight material made installation simple, and the pieces were easy to cut, paint, and customize to fit the space. Once installed and painted, they look much more expensive than expected and added beautiful architectural detail to the room. A great option for anyone wanting a designer-inspired accent wall without the cost and complexity of traditional trim work.
