The Harry Potter Locket Horcrux Mug is a rare and collectable item featuring iconic imagery from the beloved franchise. This unique mug, part of the Cauldron Crate collection, is a must-have for any Harry Potter fan looking to add a special piece to their collection. With the locket design and characters like Dumbledore and Ron, this mug is sure to bring a touch of magic and nostalgia to any brew. Made in the UK this brand new item is a treasured addition to any Harry Potter enthusiast's collection. I believe this mug is from a limited edition collection. New, but no box. The mark on the bottom edge is actual pottery that is under the glaze, and is not a defect, rack or chip. Measuring- 3.5 inches high and diameter of the rim is 4 inches. Thanks for looking.
