I had a very hard time trying to find these exact cups. The sip-a-cup glasses are all over the web but, they are the smaller, kid-sized version of this sip-a-tumbler product which is much larger. Very well constructed with built-in straw that is easy to clean with a straw cleaner brush. Very reasonably priced and the product came quickly with good packing. I heartily recommend this product.
