:: concept of design:: I like Mario's playfulness and the small mushrooms that grow on the grass after rain. I prefer the time of reading at home on rainy days. The brass bookmarks also hope that they are all natural elements at hand. These are fragments in the memory. I hope that they can be used as gifts. -The order is now made, and it will take five days to ship out. :: Material:: *Brass 3.5x2.1cm *White plain ribbon. :: Use and maintenance methods:: *All are handmade, cannot be copied in large quantities like machines and are flawless. *Pure brass is not electroplated, and there will be oxidation reaction after using it for a while. You can use a moist soft toothbrush with toothpaste or dentifrice to lightly brush the surface, or wipe with a silver or copper cloth to restore the original metal luster. *It can be put in a sealed bag if it has not been used for a long time to reduce the oxidation reaction.
