This is a set of six Shiroki stands used for the Yuino (engagement ceremony) in 2013. The long rectangular tray does not have a base, but I will include it if you need it. Please let me know in the comments. Outer dimensions: Square: 23 x 23 cm Large rectangle: 20 cm (height) x 41.5 cm (width) Small rectangle: 12.1 cm (height) x 32.7 cm (width) All are 3.3 cm high. I found two small scratches on the back of the square Shiroki stands (photos 2 and 3). We are living happily as a married couple, so I don't think the item is inauspicious.
