It doesn't get any better than a monogram and some Lilly!
You can put a vinyl decal on just about any smooth surface. Such uses are car windows, laptops, cellphones, glasses, cups, coolers, and so much more.
The vinyl used is a top notch 5-7 year indoor/outdoor vinyl. Keep in mind that if you are purchasing decals to put on drinkware, that the item will need to be hand washed. Dishwashers can possibly damage the vinyl.
