The plastic feels cheap, but what do you expect for the price. The colors are as pictured. t’s a nice color pink, not a cheap watery colored one. The button batteries come installed and can be replaced with a twist of a screw driver and your thumb. The size is a perfect tea light size and fits right into the tea light shaped hole in my holders. At Christmas Eve night into Christmas Day I left the lights turned on. It must have been about 24-hrs that past and I forgot that I left them turned on at all. In the morning, the next day, I noticed that the light was still bright.Other than the above, these lights worked great for my custom Advent votives.
