ℹ️ About the Pokémon TCG Classroom Valentine Mailbox Set

Reported in October 2026 for launch on January 27, 2027, the Pokémon Trading Card Game's first-ever official Valentine's Day box set includes mini booster packs designed for school exchanges, accompanied by cardboard packaging that folds into a functioning desktop classroom mailbox.

This studio lets trainers customize their personal classroom mailbox with custom trainer credentials, inspect the realistic folding kinematics in 3D (from a flat die-cut carton sheet up to 90° assembled walls and mail slot), drop simulated mini packs into the slot, and export ready-to-print folding craft sheets for school celebrations.

Read the explanation

The classroom mailbox begins as a flat two-dimensional die-cut sheet with five interconnected panels and four folding tabs. Adjusting the fold slider scales the target angle from zero to ninety degrees, rotating the four outer walls upward into a closed enclosure. Once folded above sixty percent, clicking Drop Mini-Pack releases a simulated card into the roof slot, marking classmates delivered on the roster.
