Zak Designs 15oz Bluey Kelso Travel Straw Tumbler Plastic and Silicone with Leak-Proof Valve for Kids, 2pcs Set, Bluey

I am actually the person who avoids reusable plastic whenever possible. I would a million times prefer glass. I feel even worse about silicone. I know it's supposed to be safe but it just doesn't seem to me like a good idea or that it may get clean enough, even though I know it probably gets plenty clean because it can be boiled. Mostly, I'm OCD and just worry about nastiness bleeding through/staining. However...I have a toddler, and desperate times call for desperate measures! XD He absolutely cannot have glass bottles. Or glass bottles covered in silicone. Because they still can break, and there's no way that is feasible right now. This is actually the only product I've found where *THE STRAW GENUINELY DOES NOT DRIP. AT ALL. EVEN WHEN UPSIDE-DOWN.* He was very frustrated at first with learning how to bite on the straw to get the liquid out, and he certainly doesn't like that he can't make a mess with it XD ... but Daddy %26 I do! It really is very impressive how well the valve works. I have found these sippies upside-down in my couch before and had this sinking feeling, but they DO NOT LEAK. Like, at all. I don't know how, but even when they are used a lot they STILL work perfectly. Reassembling them is not too bad once you get used to it. They do seem to come apart and get clean a lot more easily than say a traditional sippy cup with just a couple slits in a spout. It's harder for me to imagine that gets very clean.
