Hi, This is a tapered and straight template for skinny 20oz tumblers. I insist you measure both the cups and the images. All tumblers are NOT sized the same. These templates are what I personally use. Use them at your own risk
I have them as a png and a silhoutte file. It is transparent. I take it and lay it over my image and then resize the image to the transparent template.
When you get it all sized correctly, save it, maybe even note where you purchased your cup and design from this way you have it.
