good quality, I suppose, if usable. Suppose because I can not use them to evaluate properly. The thing is, that these clips could be use ONLY on straight plate edge stands!!! which is very important detail by the way. This HAS TO be written in capital letters on this product. Most, metallic stands at least which are the most of them anyway, are with bent edges and there the problem is - clip simply does turn itself 90 degrees away and does not keep anything anymore. Useless!
