Personalized Mermaid Kingdom Underwater Advent Calendar Box with 24 Acrylic Charms

A countdown that dives beneath the waves. The cover shows an ocean-blue scene framed in gold: four playful cartoon mermaids gathered around a glowing open clam with a pearl, an underwater palace strung with Christmas lights and topped with a star, and a Christmas tree made of seashells amid pink and red coral, starfish, seahorses, pearls and bubbles — finished with a golden name banner trimmed with holly at the bottom. Inside, 24 doors, 24 charms.

Printed On This Design
"MERMAID KINGDOM", "ADVENT CALENDAR 2026", "24 DAYS OF OCEAN MAGIC" (side spine: "MERMAID KINGDOM ADVENT CALENDAR") — personalized with the name you choose on the golden name banner.

Perfect For

• Mermaid-loving kids and ocean enthusiasts
• Twenty-four mornings of small surprises before Christmas
• A keepsake box that stays on the shelf after December
• Gifts for daughters, nieces, siblings or young friends

Gift Idea Most advent calendars are gone by the 25th. This one keeps the box, keeps the charms, and keeps their name on the golden banner.
