CD Player Cube

CD-Inspired Body Inlay Module

The body inlay features engraved details such as “MUSIC” and “FROM ZERO TO ONE”, with the outline faithfully recreating the opening shape of a classic CD player lid.

Iconic labels like “JAZZ” and other markings echo the function buttons of vintage music players.

The layout includes Random Play and Single Repeat button-inspired elements, with a small heart-shaped accent button adding a playful design touch.

This isn’t just visual nostalgia — it also features real metal dome button feedback.

A dedicated lower “music playback” button delivers a crisp, solid click, recreating the satisfying press feel of old-school portable CD player buttons. A true retro tactile stress-relief experience.

Precision Engraved Details

All characters and surface textures are created using high-precision etching, resulting in:

• Sharp, clean edges
  
• No burrs or roughness
  
• A refined, premium finish
  

Enhanced Play with Square Core Side-Push System

Paired with the Square Core side-push mechanism, the PEEK Dense Track (Version A) delivers a silky segmented motion.

Combined with the mechanical button feedback, the tactile experience is layered, immersive, and highly satisfying.

Modular DNA – Unlimited DIY Possibilities

Continuing the modular design philosophy, the 01 EDC Square Core retains its full DIY capability.

Users can freely customize the feel by:

• Replacing track plates
  
• Adjusting springs
  
• Changing bead configurations
  

Switch between different segmented feedback styles to create your own ideal tactile setup.

Universal Compatibility Across the Series

Mix and match freely to build your personalized EDC setup.

Magnetic Attachment – Tool-Free Upgrade

The inlay attaches via strong magnetic mounting, requiring no tools.
