Starbucks 2004 Christmas “holographic”cold cup.

Starbucks Double-walled "holographic.cold cup" with lid. 18oz size. Approx size 2.5" across bottom & 3"across top: 71/8" high. The colors of trees, etc inside change colors as you turn it. Can't remember what that style is called. Used maybe 2 times. Packed away every year after Christmas with other holiday cups. No scratches or flaws I saw. Smoke free home. Almost "Vintage".
