This is the SEED SUPER Gold, a high-end eraser housed in a metal case and a traditional case. Nowadays, a wide variety of erasers are available, including affordable and easily accessible ones, those specialized for erasing performance, and those with rich designs. Among them, the Super Gold, which is a bit pricey, is positioned as a luxury item among erasers. It's a carefully crafted masterpiece, featuring the now-rare "corner rounding" process and using a natural rubber compound, which is the origin of erasers. Many people seem to display it as a collection, feeling it's too precious to use. The contrast between the gold aluminum sleeve and the white eraser gives it an even more premium feel, making it a satisfying item just to look at for eraser enthusiasts. The Super Gold is satisfying enough as a nostalgic collection, but its unchanged feel from the past is also popular. Because it uses a natural rubber compound, it is strong and less likely to break. Thank you for viewing.
