The Kairos Zerotini tumbler is a small, highly portable 210ml bottle. It comes in pastel colors of pink, blue, beige, and mint, and has a handle attached to the top for convenience when moving. You can produce it as a promotional souvenir by engraving a company logo or text using silk screen printing or laser engraving. Production takes 4-5 days after design approval, and you can add gift wrapping service through separate options.
