This Neowise side table is easily assembled in just a few minutes by slotting the panels together and fastening them with black rubber or colored silicone O-rings. The black rubber rings are the primary option for this piece of furniture. However, for a more playful look, you can choose from additional silicone O-rings in four colors: neon green, pink, yellow, and orange. Moreover, the neon green and pink rings glow in the dark!
