This is Lite-Up Straw is awesome. It will get you some glow in your glass at night. The Lite-Up Straws has 3 different lite-up modes activated by a switch. It is 12” in length and it will last for dozens of hours when used intermittently. It is not dishwasher safe, you will have to rinse with warm water before and after use. You can’t get that for big party use because a set of 4 will cost you 15 bucks.
