- An ideal gift for Nurses Week, this 24 oz Chameleon Nurse Tumbler is perfect for showing appreciation. With a reusable lid and straw, the tumbler changes colors with the addition of ice: from Red to Coral Red, Yellow to Emerald Green, Blue to Cobalt Blue, and Orange to Tangerine. Note: Straws for this item are not included in the individual gift box, but rather bulk packed in the shipping master carton.
