Sticker set - Infinity Spirals Out Creation
These are 5 inches tall and I went with the best for printing, Sticker Robot. These are made to last. Here's a quote from their site:
No one can beat our quality. We will take the quality challenge with any sticker printing company on the planet. Seriously.
In order to print our custom outdoor stickers, we use the highest quality materials and inks available. Most companies use the cheapest materials they can get in order to save money. Our sticker material is custom made to our high standards.
Each silkscreen sticker is run through the press 7 times! We add 3 clear coats of Gloss UV-Protective ink and 4 passes of color. That, mixed with our special printing technique results in the best and highest quality stickers on the market.
