I still advise you to apply for a patent to protect your rights. Even if you find someone who is willing to cooperate with you and you have developed your own production and sales model, due to the low technical content of this product and you have not applied for patent protection, other manufacturers will see your sales. If it is good, it will definitely be imitated or copied and the same type of products will be launched. In this case, market competition will become increasingly fierce and profits will be very low. Moreover, your market share may not necessarily be your number one. If this continues, it will only lead to vicious competition and there will be no money to be made.
