Ordered 10 buttons with black, raised head. Seller sent 2 different kinds. They match the description but are somewhat different. On the first kind the black finish is shiny and on the other it is matte. The first has a blue base and the other a white base. The blue version has more freedom of movement and works when partially depressed. The white version is stiffer and needs do be completely depressed. I can't use both type on the same project....
THANKS
