Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard. Installation method: 1. Firstly clean the fish tank on the back of the glass, and then spray a few of water with liquid detergent on the glass uniformly or wipe with wet cloth.(to reduce the viscosity of the glue) 2. Tear off surface protection film of background, and start to attach slowly. If it appears bubbles, you can rip it off and spray some water at the bubble and then paste it again. 3. After putting it on, use the scraper or touch to check if there are any air bubbles. If there are any air bubbles, you can use the needle to puncture them or use the scraper to squeeze out and smooth them. 4. If the water is not squeezed thoroughly, the glue will turn white after being taped, use hair dryer to dry it and then affix it and smooth it. (Tips: Before use, the creases on the stickers are normal. It is not a product quality problem. After peeling off the film on the surface layer and pasting it on the wall of the fish tank, the creases can be flattened without affecting the effect.)
