The stronger and more evenly spaced the horizontal stripes in the background, the more convincing the stealth illusion will appear to observers.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this lenticular illusion sheet suitable for outdoor use?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The sheet is made from durable optical-grade plastic designed for both indoor and outdoor performances. Avoid direct prolonged exposure to intense heat, which may cause warping. Store flat in a protective sleeve when not in use to preserve the optical surface.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I clean and maintain the lenticular grating surface?\u003c\/h4\u003e\n\u003cp\u003eA: Gently wipe the surface with a soft, lint-free microfibre cloth. Avoid abrasive materials, solvents, or sharp objects that could scratch the prism ridges. Even minor surface damage can affect the quality of the optical illusion, so handle with care and wear gloves during performances.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between the 50×70 cm and the 30×20 cm sheets?\u003c\/h4\u003e\n\u003cp\u003eA: The large 50 × 70 cm sheet is ideal for full-torso or full-body illusions on stage, while the compact 30 × 20 cm sheet works perfectly for close-up demonstrations, partial concealment effects, or performances in tighter spaces. Having both gives you flexibility across different performance settings.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What kind of background works best for the lenticular grating stealth illusion?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Backgrounds with clear, repeating horizontal lines work best — such as staircases, horizontal tile patterns, venetian blinds, or rolling metal shutters.
