This is not a complete set. It is a set of 3 out of 4 types. I tried turning on the lights a few times, but I put them away quickly. Since these are gachapon toys, those seeking highly detailed items should probably refrain from purchasing. From the beginning, there were some spots of color fading on the jellyfish's umbrella part. Please check the condition in the photos. This product requires assembly. I plan to ship it unassembled via Yu-Packet Plus.
