This set of reusable straws are great for traveling. The straws are made of BPA free, food grade silicone and can withstand extreme temperatures so no worries if you accidentally leave it in your car on a hot day. The set comes with four straws in different colors so each family member can easily distinguish their straw for everyone else’s straws. Each straw comes in a carrying pod with a loop for hanging. Clip it on a bag or backpack when you go out so it will always be handy when you need it. The storage pods are only about 3 inches tall and the straws are 8 inches tall which is the perfect compact size for traveling. The straw is super flexible with ridges to show exactly where it should be folded to fit neatly back into the storage case.
