CMS MAGNETICS - (6 x 8 Stainless Steel Surface Plate 1mm Thickness 48 in² Flat Ferromagnetic Metal Sheet Board to Hang Your Magnets, Mount on Walls, Cabinets, and Fridge to Protect From Scratches

Buen producto solo que en un lado la terminación no es igual, está áspera, los otros tres perfectos, para lo que lo necesito es importante que no me lastime.

I use it as a “magnetic building board”. It is fantastic for holding small parts in place with magnets while the glue sets or when I'm airbrushing. It has made complex assemblies so much easier specially for when I work on small scale items such as N or Z scale and 1/700 scale models. It is sturdy and perfectly flat making it an ideal surface. I have three of these; one is dedicated for airbrushing and when I feel there is enough layers of paint I usually clean it off with IPA a bit (I use Acrylics). I have one that’s bare metal and one that I have covered with self adhesive vinyl film. Which one I use is based on what I’m building, material, glue etc. My only word of caution is that the edges can be quite sharp right out of the package. It's not a big deal, but I'd recommend taking a moment to lightly sand or file them down just to be safe and avoid any accidental cuts. If you're a modeler looking for a magnetic-receptive work surface this is a 5-star tool that has earned a permanent spot on my bench.

I got a 6"x8" plate down to the exact measurements. The holes measure roughly 5 3/4" and 7 3/4" from each other respectively. Each predrilled hole is just around 4mm big. This small one held up well enough for smaller crafts, having a decent weight to act as a baseboard. This type of stainless steel is ferromagnetic. It's not scratch resistant obviously, so ensure whatever magnet you put on it is smooth. The edges are still a bit sharp from machine cutting, so they would need to be sanded if they are going to rub up against anything you place them on.

Bought these to hold magnets that bought on vacation. Perfect!

It is exactly what you want. Good, thin, (magnetic attractive.)
