Protect your products and services with these 100 pack tamper proof warranty stickers. Each label leaves a clear void message when removed, giving you instant visual proof of tampering. Made from brittle PVC film, these security seals break apart if someone tries to peel them off, making reapplication impossible.

These warranty void labels are ideal for electronics, appliances, and any product that needs a secure seal. The adhesive grips firmly to most clean surfaces, ensuring that the sticker stays in place until someone attempts removal. Once tampered with, the void pattern is unmistakable, helping you spot unauthorized access right away.

Each sticker measures 20 mm by 10 mm, which is small enough to fit on screws, battery compartments, or warranty panels without looking bulky. The pack includes 100 pieces, giving you plenty of labels for multiple devices or ongoing service work. Whether you run a repair shop or sell electronics online, these seals add a layer of protection that customers notice.

Usage Scenario

Mike runs a small laptop repair shop. After fixing a customer's computer, he places one of these void stickers over the bottom case screw. Two weeks later, the customer claims the screen broke on its own. Mike checks the sticker and sees the void pattern exposed, meaning someone opened the laptop. He explains that the warranty is void due to tampering, saving his business from an unfair replacement claim.

Micro Comparison

Unlike standard paper stickers that can be peeled off cleanly and reapplied, these brittle PVC labels break into pieces during removal. The void message is embedded in the adhesive layer, not printed on the surface, so it cannot be scraped off. This makes them more reliable than basic security seals that only show a simple cut mark.
