    KOL’s positive reviews and recommendations

    Rantra's first transformation technology, whether you want to replenish water, high protein shaker cup

    Or the occasional indulgence of a hand-cranked drinking cup, everything is covered and you can play freely and freely as you like, which is enough for Rantra!


    You can do unlimited tricks with water cups, I can only admire Rantra🤣Once you use it, you really can’t go back🙏🏻


    Rantra is enough to be free and unrestrained🤩
    Everyone needs the Rantra tumbler!
    There are a total of 3 colors: fashionable black, cream white, and grapefruit red~
    The fashionable design and matching are addictive💕


    One cup of Rantra is enough to be used freely and freely ✨
    The ice retention effect has been tested and ice cubes with less ice can last for twelve hours🧊
    The capacity is also 700ML, which can accommodate large cups from beverage shops🥰


    The exclusive high-proportion plant fiber material is used to reduce the use of plastic by 50%. It can also be turned into a plant pot or a non-staple food container to let Rantra play as he pleases✨🩷


    The cup sleeve is made of exclusive high-proportion plant fiber material

    Not only does it protect the cup body, it can also be used as a plant pot, for holding snacks and biscuits, and as a storage box👏🏻


    Rantra tumblers are worth more than one cup

    Let me have a shaker cup, a beverage cup, a warming cup, an instant noodle soup cup, and a coffee cup at once

    Pretend to be whatever you want!

    Catalina Travel Notes

    The outer surface of the cup body is made of 304 stainless steel + the inner tank is coated with medical grade 316 stainless steel!

    I thought that the stainless steel eco-friendly cup should not be light in weight.

    Unexpectedly, the cup plus lid (excluding the strap) only weighs 470 grams~

    It is actually lighter than 600ml mineral water. It does not feel bulky when you put it in your backpack or handbag when going out!
