Starbucks Awesome Rainbow 24 oz Cold Tumbler with Iridescent Prism Dome Lid -NWT

Very cool Starbucks Rainbow 24 oz. Cold Double Insulated Tumbler with Iridescent Prism Dome Top New with Tag Pleated outer with Rainbow 🌈 inside from Orange to Pink to Purple… and a purple straw. Excellent condition without any issues Normally I’m able to do pretty good research on my Starbucks collectibles; but not this time! I couldn’t find a release season, year or even a stock photo. Could it be a special release? Fellow Posher’s if you have any additional info on this very cool Cold Tumbler… I welcome any help. I always strive for complete customer satisfaction and next business day shipping.
