Hirono wears a dark bird costume beside a red envelope and a Dear Birds sign. My Deepest Secret is the regular Hirono design in the mixed-character Dear Birds Series Fridge Magnet Blind Box range. This is a flat magnet accessory, not a vinyl figure.

POP MART lists MDF and soft magnet as the materials, with a range-level length of 8.3-10.1 cm (3.27-3.98 inches). The official width text contains a mismatch, so a metric width is not reproduced here. The official website release was July 23, 2026. Age guidance is 15 and over. Check whether the listing is a sealed blind box or a confirmed My Deepest Secret design, and confirm the dimensions with the seller.

Compare the seller photos, packaging, accessories and condition before buying. Search results may include other Hirono releases; check the full product name. No current stock or price is promised here.
