Anytime I buy an item off Amazon with anything labelled "3m" , you just entered the craptastic lottery. You either get exactly what it's supposed to be , or some weird old horse-glue substance most likely brushed onto some gum wrappers that were thrown in the trash. This stuck first time , it sounds like it's built into the item you stick it to. I'm not sure if it's 3d printed , but it looks like it , the plastic feels like a kind of solid plastic I didn't expect. This item stuck to my desk and just became a part of my daily life seamlessly. Products that do their job THIS well , sometimes you just forget about them , until you try to save a buck and end up with a seriously basd imitation.
