Best smoothie straw cup for toddler?

I saw an awesome one sold in Australia but with the cost of international shipping put everything at $76 not including tax!! I’m in the US and trying to find a good on the go smoothie cup for my 21 month old. One with a large enough straw that a smoothie could run through and toddler proof. I’m not finding many options on google but saw this when I typed in “smoothie cup for toddler” and it looks nice but I’m just wondering if the straw will be wide enough? Anyone use this for smoothies that can tell me? Thanks.
