Don't know what you need from the "straw cups" or how old your child is, but I was tired of the pieces and parts that were hard to clean, got lost, would grow mold if not enough air was allowed to circulate, and were hard to drink through...and found a couple that I still keep around today, even though my kiddos are now 7 & 10 years old (nice to have for car rides, or little visitors!): Tupperware makes a set of four plastic cups with lids that attach tightly and has a silicone slitted opening that allows you to insert a straw (not leak-proof, but pretty safe), Tommy Tippee makes a cup that has an inverted lid with a hole that can be used with a straw, or just to slow the liquid coming out for cup-training (won't prevent leaks, but makes for less mess when the cup is accidentally knocked over), and my favorite is not currently available: a plastic, double-wall, "Grande" or "Venti" cup from Starbucks that has a screw on lid with silicon gasket (preventing leaks) and a reusable straw with a bump on it so it can't be pulled out of the lid when the lid is on the cup (if you've ever had a little one discover the "joys" of flicking liquid everywhere as the pull the straw out of a traditional plastic lid, you know what a big deal this is)! Good luck to you!!
