This Kebica Rainbow Paper Weight is a square, block-style desktop accessory designed with both functional weight and optical flair.
Based on the images, here is a breakdown of its features:
Shape and Form: It is a thick, solid cube or block made of clear glass or acrylic. The top surface features a distinct, smooth circular indentation (a concave recess) that creates lens-like optical distortions when you look through it.
Color Effects: While the core of the block is completely transparent, the outer vertical corners and edges are treated with a vibrant gradient of primary and secondary colors (including blue, red, yellow, and green). Because of the clear material, these colored edges catch the light and refract beautifully throughout the entire piece depending on the angle you view it from.
Packaging: It comes in a bright yellow and orange cardboard box branded by Kebica Stationery (established in 1959). The packaging proudly labels it as a “Rainbow Paper Weight” and notes that the company is an ISO 9001-2000 certified brand.
