Marspark 500 Pieces Silver Security Tamper Evident Seals Stickers Void Original Genuine Authentic Hologram Labels Tamper Proof Evident Stickers Sequential Serial Numbering, 0.24 x 1 Inch

It's nice that it's individually numbered. Not big enough to use as a seal or to seal a bottle lid to bottle. It doesn't adhere properly in that format. It does well on one surface, however does peel off easily. Otherwise worth the purchase to number.

These were a bit smaller than I anticipated, but they work great. Also good as inventory tags since they are uniquely numbered.

They look like they will work but...... they dont stay stuck well. Can be remove with little effort and zero security benefits.

They stick well and do the job, though a few tore when peeling. Great for business to show if product was tampered with in shipping

✅ Practical Testing and Honest Impressions I ordered these expecting something closer to what the listing photos showed, but the reality is different. The stickers are very small (just 1 inch long and 0.24 inches wide) so they don’t cover much surface area. They adhere fairly well to glass, paper, and metal but struggled on plastic and cardboard. Despite their size and thinness, the sequential numbering makes them useful for tracking, and at this price point, they’re still a good value if you know their limitations. ✏️ What to Know in 30 Seconds • Pack of 500 silver tamper-evident stickers • Sequential serial numbering for tracking • Each sticker measures 0.24” x 1” (much smaller than images suggest) • Works best on paper, glass, and metal • Poor adhesion to plastic and cardboard • Thin and delicate, requires careful handling • Available in 500- or 1000-pack options 📝 Design and Build These are very slim, reflective silver labels with printed serial numbers for identification. They’re thin enough that handling takes some care to avoid tearing or curling. The size is the biggest drawback, as the product images make them look larger than what’s received, which can lead to disappointment if you expected broader coverage. 🧐 Practical Use They work as a tamper-evident seal on envelopes, paperwork, or glass jars, but their short length prevents them from wrapping around larger items as shown in some promotional photos. Adhesion is inconsistent...strong on smooth metal or paper, much weaker on plastics and textured surfaces. ⭐️ Advantages • Sequential numbering adds a tracking element • Affordable bulk value (500 or 1000 packs available) • Decent adhesion on smooth surfaces like paper, glass, and metal • Useful for small-scale tamper-evident needs ⚠️ Considerations • Much smaller than depicted in images (only 1 inch long) • Weak adhesion on plastic and cardboard • Very thin and somewhat difficult to handle • Misleading product photos may cause size confusion ✅ Best For • Sealing envelopes, jars, or documents where small security labels are enough • Low-cost tamper-evident needs with a tracking feature • Users who only require seals for smooth, non-plastic surfaces 📌 In Conclusion The Marspark security stickers are a cost-effective option for tamper-evident sealing, but they’re much smaller and thinner than expected. They stick well on paper, glass, and metal but perform poorly on plastic or textured materials. If size and surface limitations aren’t a concern, the sequential numbering and bulk pack still make them a practical buy. ⭐ Star Rating: ★★★☆☆ (3.2) Honest, detailed, and unbiased reviews ensure that every purchase may be completed with confidence. This feedback is based on real experience, offering clear insights to help consumers make informed decisions.

Still using and using. Never ending labels. They're good.

Don’t expect these to stick to plastic dram bottles. When used on paper they work as they should. I ended up taping the plastic area with foil tape first then these on top of the foil tape.

As ordered

Good product

Last update: I am fad up with these so called "anti-tamper" stickers. Revising 2 stars to 1. They come off from any device or surface I try to stick on. No point in using these as anti-temper stickers. Don't waste your money. Update: Rating downgraded from 3 to 2 stars. Updated review: These stickers are not sticking well on chassis of my computers as mentioned in original review below. The worst part is that they are coming off after 2 days of remaining on surprise. If these stickers were to fell off then what's the point of using these as 'anti-tamper' stickers. Disappointed. Original review: I anticipated slightly bigger size based on the advertised dimensions so probably use a real world scale to see if the actual size would fit your needs. One other problem I noticed is that these stickers are not leaving the 'void' mark on some of the surfaces (e.g. the black painted surface of Dell and HP PCs). Anyhow, I got 5 sheets having 100 stickers each and probably enough albeit a bit smaller than anticipated.

Very happy with everything.
