FAQ
Q1: Are these magnets safe for kids to use in school projects?
A: Yes, they are safe under adult supervision. However, due to small parts and strong magnetism, they are not suitable for children under 8 years old.
Q2: Can I glue these magnets onto wood, plastic, or fabric?
A: Absolutely. These magnets work well with hot glue, epoxy, or strong industrial adhesives.
Q3: Are the magnets coated or plated? Will they rust?
A: No coating is applied; ceramic ferrite magnets naturally resist rust and oxidation, making them ideal for long-term indoor use.
Q4: Can I use these magnets outdoors or in high-humidity environments?
A: Yes, they can withstand humid environments. For extreme outdoor conditions, additional coating or housing is recommended.
Q5: Do you offer bulk pricing or custom packaging?
