Block Lights (Set of 4) These are LOGOS LED lanterns that can be operated with a remote control. I am selling them because I haven't had a chance to use them. They have been stored at home, so there are some scratches and wear on the outer box. Although they are unopened, they have been in someone's possession, so please purchase only if you understand this. I will pack them carefully and ship them. 【Product Details】 ◾︎Total Weight (Approx.) 530g, Size: (Approx.) 8 x 8 x 8cm Remote Control: (Approx.) 3.7 x 9.7 x 1.6cm ◾︎Brightness [LED Bulb Value] (Approx.) 240 lumens [LOGOS Standard Value] (Approx.)
