New items can indeed be cursed! Satan knows full well when something evil is made. So does God. It doesn’t matter how it was created. What matters is what it was created for. New items that have been created to use in the worshiping of false gods is one of the biggest areas where something new could still be cursed. For example, new Christmas lights sitting on the store shelf waiting to be sold, are still cursed, for it was made to celebrate the winter solstice. It is the same with chocolate Easter bunnies, a four leaf clover good luck charm, or even a wreath. If it is sold to be come a part of a pagan ritual, then it is very cursed, even before it is bought by someone. Even if it simply has pagan history associated with it, it is cursed, even if you would not be using it as such. (Take for example, a rabbits foot good luck charm. Even if you simply like the look of it, and do not think of it as a good luck charm, it is still cursed because of its history of being a good luck talisman to others in the past.) Demons do not differentiate between what an item is and what you deem it to be. If they recognize it as being at all pagan, then they will look upon it as being a neon sign that welcomes them.
Also, be aware, an item is usually owned immediately by someone. Who owns the machine that created it? Who owns the supplies needed to make it? Who owns the land upon which it was found or made? Do not think that just because it sits upon a shelf in a store waiting to be sold to someone, that it does not already belong to someone. Indeed, some of the most cursed items our family has come across, has been from items made by the unbelieving owner of a small shop. If that small shop owner is for example a Wiccan, a Satanist, a Hindu, a native American Indian, (pick any false religion,) or even an atheist, their items that they are selling are cursed. Somehow the sin of their pagan worship practices (or the sin of their unbelief,) rubs off onto the items that they sell. For some reason we have not found this to be as strong in the big box stores. Most of the everyday items, for example, that are sold in Walmart, we have not found to be cursed.
