These pins are exactly as described, they lock well, and hold on tight, but be warned, there is only one option that comes with the tin! Unless you want the default nickle-colored backing, you won’t get the tin despite that being the cheapest option of the three!Overall, the backings are exactly what you need, especially since a lot of pins now come with ribbed silicone backings that don’t hold the pin sufficiently. I ordered the silver ones expecting the tin and didn’t receive a tin, so while they look exactly as I needed, they weren’t completely as I expected. I think the color choices were a bit lacking since having black backings would also be nice since gold and silver catch the eye more when the backing is spotted, but that’s a small nitpick. Easy to use, easy to remove, and standard quality.
