round magnet 18 * 3mm ferrite wafer plastic sealed pvc magnet 圆形磁铁18*3MM 铁氧体圆片 塑封PVC磁铁

The primary function of PVC is to prevent magnets from coming into contact with water during use by the customer. Even when exposed to water over time, it does not rust or oxidize, thus maintaining its normal functionality and appearance. The biggest advantage of this “clothing magnet button” is its ease of use. The product operates through positive and negative poles that attract each other, and these are concealed inside the clothing. There is no visible button shape on the garment, which is truly described as “only the clothing is visible, no buttons at all”! It completely replaces traditional buttons, offering a more elegant, refined, convenient, and fashionable look. Calling it “a leader in the trend of button designs” is not an exaggeration!
