From Our Experience

Still love SoL the most as borosilicate glass does not retain taste, colours, chemicals and is light to carry around! Just ensure that you do not drop them.

    Got the 16oz cup & it’s such a light cup.
    I bring it with me anytime. Great for when i’m in the office, on-the-go & even at home.
    The colour makes this cup such an eye candy too! Love it~

    Lovely reusable glass cups that are pretty and lightweight. Perfect for drinking that cuppa at home or on the go 🙂

  6. Jil

    Got the 16oz one for the times I crave a solid cup of coffee, tea or bubble tea! Really love the durability, ease of removing odours and drink stains too 🙂

    I got the 8 oz one and use it to buy small starbucks/coffee bean drinks and even liho (small size). I love how lightweight is it because I take it with me in place of a bottle! I sometimes fill it up with water and take it to my classes too. What I love the most about it is that is doesn’t stain or smell like the usual metal travel cups. This way, it’s so easy to clean with just tap water whilst on the go! Definitely recommend this to anyone looking for a reusable cup. I’ve gotten so many questions and compliments over my cup. I guess it’s safe to say that it’s also a conversation starter. haha.

    Love the design and colours of this cup. Also, glass was a wise choice for me as it does not retain any colour, smell or chemicals as compared to other materials.

    I am a generally careful person so I got this because I would not have the fear of dropping it. It does not break while in my bag as well!

    Avoided so many disposables with this cup! 🙂

    Was pleasantly surprised by how lightweight this cup was, plus the design and colours are so aesthetically pleasing! I got the 16oz one and I’ve been using it every day without fail, especially since it is so easy to wash.

    got the 16oz one and i am super surprised by how light it is! looks quite huge but actually isn’t too big and fits well in my bag. it’s very convenient and super pretty too! i love that it doesn’t stain or retain any smells and it’s super easy to wash! highly reccomend if you’re trying to reduce your use of plastic cups

    I recently bought an 8 Oz one and I’m just gonna say it’s super versatile. It’s a cup that follows me everywhere around the house, holds my coffee, is easy to wash, and looks cute all at the same time! The one I got might be a bit too small to carry around the amount of beverage I desire, but that’s just another reason I might get the 16 Oz one haha. I am a bit worried about how well it can maintain the temperature of larger drinks though- it’s not a problem now as I finish a small drink quick enough.
    Besides that potential pebble path, it’s a pretty smooth n solid yes from me.
