The floppy cube family grows up: sixteen pieces arranged in a single pillowed layer, moved exclusively by half-turns that slide whole strips around the frame. Pink PETG printing and inlaid tiling give this ZePuzzles edition a soft, friendly character.

Beyond the classic 3x3x1 floppy, the extra columns add genuine spatial reasoning without ever becoming cruel - reviewers place it barely above beginner tier. The pillowed profile is functional, not decorative: those curves are what allow the strips to slide.

Fidget-friendly, brain-friendly, shelf-friendly.

Features:

• Single-layer 1x4x4 sliding puzzle
• Half-turn strip movement mechanics
• 3D-printed pink PETG, tiled faces
