They release as part of the brand’s upcoming Christmas in July sale. The palette will be free with $55+ purchase on July 16th (or available for purchase for $33). The palette is available in a Light and Deep offering with the following shades being different: Bask, Sandcastle, and Daystar.
You can get one mystery bag free with a $55+ purchase on July 13th, and they can also be purchased individually for $25 ($50 value per bag); the mystery bags will be available in Cool, Warm, and Colorful with a light- and deep-version for each variation. In the Warm mystery bag, Georgia Peach blush, Honey Babe loose highlighter, and Just Peachy eyeshadow are specific to the Deep version of the bag.
P.S. — I don’t have the Cool/Colorful bags at this time but should have them in a week or so (after they go live, FYI).
