Mexican Flower UV DTF Wrap Transfer 16oz for Glass Libbey Jar. Most wrap dimensions are 9.4 x 4.4 or sized around there for proportion Simply peel, stick, rub air bubbles out, and remove top film for a permanent waterproof decal. These decals are perfect for Libbey jars, glass beer can & snow globe tumblers (16oz) To apply decal to a surface, follow these easy steps: Step 1: Clean and Prep Wash your cup with soap and dry completely. DO NOT USE ALCOHOL as it will break down the adhesive. Step 2: Position and Secure Place the cup on the hard, straight surface, then start peeling the backing as you roll the cup. Once the decal is on the cup, take time to push the decals onto the surface. I usually push between 3-5 minutes with my palm, using body temperature to activate the UV DTF adhesive. Doing this will make your peeling step so much easier, and decals will have less lifting. Transfer is NOT removable or adjustable once it is applied to a surface. Step 3: Remove Backing Very slowly peel off the backing paper from the decal, ensuring it doesn't stretch or tear. If any part of the design lifts up as you peel, go back, gently push down on that area, and then resume peeling. Step 4: Smooth It Out Use your fingers or palms to smooth out the decal starting from the center and moving outward. Step 5: Activate DO NOT wash or use the finished project for 24-48 hours to allow the adhesive to strengthen on the glass or cup.
