Frequently Asked Questions

Q: How do tamper proof void security stickers work?

A: These tamper-evident stickers use a special adhesive layer that bonds strongly to surfaces. When someone attempts to peel or remove the sticker, it leaves a visible "VOID" pattern on both the surface and the sticker itself — immediately revealing that tampering has occurred. Because they are single-use and disposable, they cannot be reapplied.

Q: What surfaces can these 40×20mm security stickers be applied to?

A: These void security stickers adhere well to a wide variety of smooth, clean surfaces including electronics casings, cardboard packaging, glass bottles, plastic containers, metal panels, and document envelopes. For best adhesion, ensure the surface is clean, dry, and free of dust or oils before application.

Q: Are these stickers suitable for product warranty and anti-counterfeiting purposes?

A: Yes. These blank matte silver security seals are widely used as warranty protection labels, product authentication stickers, and anti-counterfeiting seals across industries including electronics, cosmetics, pharmaceuticals, and retail packaging. The blank design makes them versatile for any branding or operational use case.

Q: What is the difference between the 100-piece and 200-piece packs?

A: Both packs contain the same tamper proof void stickers (40×20mm, matte silver, blank). The 100-piece pack is ideal for individuals or small businesses, while the 200-piece pack offers better value for higher-volume sealing needs such as large product runs or ongoing shipping operations.
