content: Have never seen security stickers for sale with the word 'calibration'. But these things come close:https://www.aliexpress.com/item/1005003491663627.htmlhttps://www.aliexpress.com/item/1005007484845820.htmlhttps://www.aliexpress.com/item/1005001729519676.htmlhttps://www.aliexpress.com/item/1005005962331152.htmlSearch further on Ali, there are plenty of other security seals available. Also in tape format.That said, the value of the equipment you'll apply it to will not increase much as anyone can buy those stickers for cheap. The ones with serial numbers might help a bit with the tampering as it would be difficult to acquire the same numbers.

content: They are very common in the USA. Not trying to use them to increase value of anything I sell, just for myself. Mostly to seal the zero adjust screw on analog meters.I found these but $18 + $10 shipping. I guess I'll just wait until I find more stickers I want from them to get the free shipping for $30 orders.https://www.smartsign.com/fos/Destructible-Seals/Calibration-Void-If-Broken/SKU-QC-205-DV075

content: Why do you need to put stickers on your own equipment to preventyoufrom tampering with it?Go look for "warranty stickers" on Ebay. You can find all kinds of stickers for less than $10 and with free shipping.Here are two examples; 205407317559 (20 each for $2.95) and 204296919406 (100 each for $6.95).

content: For personal use why not buy the sheets of round stickers for a buck or two at the stationary store or Walmart and then print whatever you want on them. It takes a few minutes with MSOffice, LibreOffice or Inkscape to set it up but after the first round you can have as many as you want.

content: The usual manufacturers of pages of self-adhesive labels have web links for “templates”, such as tables in Word, for printing labels on printers compatible with the materials (laser or inkjet).

The only 'calibration void if removed stickers' on there under $20 are these ones:https://a.co/d/cV07pg0I might settle for them. I didn't want ones with the spot for writing in the middle. Can't be too picky I guess. Figured someone here may have them by the thousands and could shoot a few in the mail..

content: Quote from: CatalinaWOW on June 10, 2025, 05:38:14 pmMaybe a buck or two in the 90's. The ones I was finding were like $30 a pack. I did find some cheaper Avery 3/4" round printables on amazon for about $12 after posting this thread, so yeah I could do that in that case.

content: Quote from: pac1085 on June 10, 2025, 11:02:01 pmIf you are really on a tight budget go to Goodwill or other thrift store. People buy those packets (of 50 or 100 or more) to mark prices at yard sales and the like. And throw the remainder in the collection bin. They are marked way down there, and I have even seen them sold priced at something like $0.85/lb.

content: ^Those stickers would have saved me a lot of grief when I was selling expensive timepieces on eBay. There were buyers who remove the part they needed and try to get a refund. When eBay changed to buyer only support (and dropped sellers being able to neg a buyer), I became a buyer only; although I have dipped my toe into selling electronic gear I do not need lately. Like the man said as he passed the third story window "so far so good".Beware BTW, eBay removes negs on sellers for several reasons, so you cannot trust those 100% ratings. It involved a fake print I returned and I negged him to warn others, but eBay removed it w/o investigating. He turned right around and listed it again as original.

content: Quote from: Stray Electron on June 10, 2025, 05:02:58 pmI think a common use for the Ali ones is to make used/fiddled-with equipment new/untouched again. Not saying the OP is doing this, but that's why some of those stickers exist.
