How to make stronger power button?
– Magnets in same size, material better, power stronger
– Magnet in same material, size bigger, power stronger

Which silver color is better? Zinc or Nickel Plating?
– Zinc will be at lower cost
– Nickel will be shiny, and easy to pull out

What’t packaging will Richarms offer?
– for big size magnet, we might suggest to add divider so that customer will easy to pull out each one
– Standard Packaging is plastic bag + box + carton
– Degaussing Packaging is plastic bag+box+form box+carton, for some voyage ask no magnetic power tested on the outer box
