These are nostalgic Showa-era retro LED elements. There are 6 bags, some of which have been used, so the number of pieces has decreased. Colors include white, yellow, green, and red. Ideal for experiments and electronic projects. In addition, the following parts are included: LED caps: white and yellow, 2 bags each. LED sockets: 3 bags. LED assembly bracket kit. These are several decades old, so their operation is not guaranteed. Please purchase only if you understand and accept this.
