Re: Can someone ID this type of snap button?
It is called a "Lift-the-Dot" fastener. I don't want to sound like a jerk, but it should be printed directly on top. They are made by the TRW company. You can find them at any local upholstery shop and on-line.
How many do you need? Send me a PM with your mailing address and I will mail a few to you, no charge. (I'm an upholsterer).
