Frequently Asked Questions

ISHU technology is made up of highly reflective material using nano-spherical crystals coated with various alloys to produce a significant inverse retro reflective coefficient.

While we have done our best to ensure that all of your expectations are met, for best results please adhere to the following instructions:

• Mobile Flash: All of ISHU’s products work best with mobile flash. Effects are diminished when used with other forms of flash photography such as SLR cameras.
• Lighting: Best results are visible under low light conditions and at night. Please be aware that the products, including the scarf, will not have the desired effect in broad daylight.
• Phone Camera: When taking a picture, a phone camera increases the “invisibility” effect when focusing on the item. This is achieved by clicking on the product on the phone screen.

Hand wash only below 30°C
For hats and leather goods wipe clean with a damp cloth.
