This is a set of 5 hole-through neodymium magnets. Orders placed by 5 PM will be shipped the same day. Orders placed after 5 PM will be shipped the next morning. They will be shipped individually screwed onto a wooden base. Please remove them one by one when using. Be careful not to bring the magnets close to each other, as they have a strong attraction. When attaching the magnets to a wall with screws to hang tools, we recommend using magnets that are 20mm or longer. Tools may fall off if you use magnets that are 15mm or shorter with just a light touch. (Please try 20mm; the magnetic force is noticeably different from 15mm.) 【Important Notes】 ★ Please be careful to prevent children from swallowing the magnets. Swallowing magnets or button batteries can have serious health consequences. ★ We recommend removing your wristwatch when handling the magnets. Especially with high-end mechanical watches, the internal mechanisms may become magnetized and malfunction. It is also safer to keep them away from other electronic devices. ★ When neodymium magnets stick together, slide them sideways to separate them one by one. Bringing the magnets close together will cause them to strongly attract, and the impact may cause the magnets to chip or break. ★ Neodymium magnets are formed by solidifying magnetic powder at high temperatures, making them prone to damage. Please avoid strong impacts. When tightening screws with a screwdriver, be careful not to overtighten.
