These buttons are right at 1" tall with shank backs. Made of plastic. Great detail and color. 3 per pack. I DO SHIP International. Please message me and we can work out the details. Please note that I do Free Motion Long Arm Quilting, if you are interested in seeing my work go to Sneeze Weeds Studio on facebook, there are photos and pricing sheets. I have been custom quilting for 15 years. Contact me if I can help.
