Love Heart Lithophane Box – Keepsake Box & LED Night Light with "I Love You" Wall and "You & Me" Lid

A heart-shaped keepsake box that turns into a glowing night light. Drop a 38 mm LED tea light inside and the whole wall lights up with an original pixel-art lithophane: "I LOVE ... YOU", twinkling stars, heart-shaped hot-air balloons, a crescent moon and soft clouds. The lid is a second lithophane: two interlocked hearts with "YOU & ME – ALWAYS".

By day it is a clean white heart box for rings, notes, love letters or small gifts; at night it is a warm, cosy mood lamp. A perfect gift for Valentine's Day, anniversaries, engagements, weddings or "just because".
