These are nicely made, and come as 4 quater circles on a PCB frame. You have to cut them out yourself. This requires a bit of care, becasue they are set at an angle. I cut the frame in to 4 first then removed the frame from the quater end so I could get a decent cut without stressing the other quaters. The front finish is black, which is quite smart looking. If you want to make a decent looking full circle its worth making a template to guide you whilst soldering the full ring. For those looking to make a clock should note that the Pixel order is anti-clockwise, so you need to do some math to compensate, such as using the Map() function if programming in 'Arduino'. MinPixel = map(mins, 0, 59, 59,0); If you are using the Neopixel Libary you will need to define the type to: PIXEL_TYPE SK6812RGBW Don't for get to add the value for the white pixel: strip.setPixelColor(i,255,0,0,0); Other than that if you have used Nexpixels before then these are easy to use. Enjoy
