• Shinju is a collection of 15 High-Res Holographic / Iridescent Textures.Holographic foil is THE hardest effect to copy with mockups.
• It's really difficult to find good and realistic packs of Holographic textures... so we made our own!
• Unlike other Holographic texture packs, these are actual photographs (not gradients) taken at the best angles to look great on your mockups and other uses. As with our other products, we've kept in some lovely imperfections (wabi-sabi) to keep them authentic.
• The pack also includes a set of overlays for corners, bends and edges. This means you can add realistic details where light stretches and bends!
