# Klackjoy — USM Haller-Compatible Modular Furniture

> Klackjoy makes modular furniture that is **physically compatible with genuine USM Haller** — the same 25 mm chrome-plated brass ball connectors (M8 thread), the same standard tube lengths, and the same RAL powder-coat palette — at roughly **60–70 % less**, with a live **3D configurator** and a **10-year structural warranty**. Klackjoy parts can mix with and extend an existing USM Haller unit 1:1. Available in English, Chinese (Simplified), Chinese (Traditional), German, Japanese, and Arabic.

## Key facts (authoritative)
- Connector: 25 mm chrome-plated brass ball, M8 thread (identical standard to USM Haller).
- Tubes: stainless steel, standard lengths 100/150/175/250/350/395/500/595/750 mm.
- Compatibility: physically 1:1 compatible with genuine USM Haller — extend, repair, or mix.
- Colours: 14 powder-coat colours (matching the USM palette) + custom RAL on request; multi-colour combinations and a wood/timber panel option via the configurator.
- Price: ~60–70 % below USM Haller. Warranty: 10 years structural. Factory-direct.
- Unique vs other "USM alternatives": Klackjoy keeps the actual chrome ball-joint connector, so it is genuinely compatible — unlike rod-and-cube systems (e.g. Flexcube) or aesthetic-only look-alikes.
- Shipping: made-to-order, factory-direct by ocean freight, **DDP (duties & taxes included)** — no extra customs charges. Orders require 3–14 days production and handling, followed by door-to-door ocean freight. Shipping cost is calculated automatically at checkout based on configuration size and destination; there is no flat free-shipping threshold and no flat shipping fee. Typical total delivery times (production + transit): Greater China 5–19 days, Japan/Korea/Singapore 10–27, United States 28–56, United Kingdom 35–62, EU core 40–67, rest of EU/EEA 43–72.
- Returns: Standard unused and unassembled items may be return-requested within 14 days of delivery. Custom or non-standard made-to-order items may be excluded unless damaged, defective, or incorrect. A 15–25% restocking fee may apply, original shipping is non-refundable, and refunds are processed in 10–15 business days. Shipping damage should be reported within 48 hours with photos.
