These darn pins rock my world! I have never before worked with a pin that is this thin and it is FABULOUS. It is very, very skinny and very sharp. Because the head on these pins is so small, Karen says she likes to spill the pins onto a piece of felt, making it easier to pick them up. There are 45 pins in each little plastic tube. When the original Perfect Pins were being manufactured Karen requested a smaller size. The answer was, "No, we cannot do that." She kept pestering them and the rest is herstory!
