Compatible with Flsun V400 3D Printer Build Plate Round Dia 309mm Textured PEI/New Smooth PEO Magnetic Spring Steel Flex Bed PEO PEI Sheet (Color : Without Base, Size : Dia 309mm)

I needed a replacement printing surface for my V400 because I scratched the original with the printer head pretty bad. This seems to work like the original, sticks to the magnetic bed fine. There are 2 sides, a PEI side that is similar to the golden color side on the original and a smooth side. I've printed on both sides now and the prints adhered fine with no glue. The PEI side texture is just like the original. The smooth side does produce a faint triangle pattern that you can see in the photos. I actually prefer the results from the smooth side so far. Just so you are aware, this shipped from China (I didn't realize that when I ordered) and it took about 2 weeks and came USPS. It was well packed with a protective plastic over the smooth side, in a bubble wrap, then cardboard, then a padded mailer; probably almost indestructible anyway being made of steel. I'd recommend it.
