I bought these punches from Hobby Lobby. They are priced $9.99 (for all 3) normally, I used a 40% off coupon to save a little bit. I bought it for the single dot punch (the middle one).
Today I was finishing a pair of earrings on kidney wires for a gift, with no way to display/store them for shipping. Light bulb minute, I thought maybe the ribbon slider punch (it looks like 2 lines) would work. It did!
