【推荐3】A Reminder Bracelet (手链)
Description
The “Within Good” product line was created as a way to encourage positive thoughts and good deeds.
In one simple design concept, it is a wearable reminder to people of all backgrounds that “Within Good, There Is God”—a pure message that no matter what you are going through, you can always do good, and the spirit of love, known as God, is always within us and in the world.
Within Good is not intended to be a religious bracelet. In fact, one of the reasons why the “God” reference appears on the inside of the bracelet is because it is personal to the wearer. The company co-founders say their concept was to go back to the basics of doing good for yourself and others: “At the end of the day, God symbolizes peace, love, connectedness, purpose, and any other word that makes you feel GOOD.”
Over many months, the logo (标识) turned into a symbol represented by the double “o” in Good and interlocking with the G and D. “Within Good” is printed on the top of the bracelet and on the back is printed, “There Is God”. The rope symbolizes strength, and a strong connection between Good and God (always inside us).
Why This Is a Good Gift:
Looks Great: Casual yet classy styling, in a unisex (中性化的) design.
Gift Packaging: Each bracelet arrives inside its own little drawstring bag, ready to give away without wrapping (包装).
Discount: $29.99 $26

“My cow’s ill,” the farmer said. “I don’t know what’s the matter with her. She’s lying down and won’t eat. She’s making a strange noise.”
