Size Guide
Ring and watch fit charts, plus Fiber and CO₂ work-area limits.
Fiber · G2
Field ~150 × 150 mm
Flat metal within the galvo field. Rotary for rings / pen barrels — cylinders don’t use the full flat area the same way.
CO₂ · MEGAS
Bed ~700 × 350 mm
Flat cut + engrave only. No rotary on MEGAS in this storefront. Larger art may need tiling or a B2B quote.
Bare-metal jewelry and tools are Fiber only. CO₂ is not sold as equal permanence on bare metal.

Fit tips
- Measure ring size at the end of the day when fingers are warmest.
- If between sizes, choose the larger size for comfort bands.
- Watch case size is diameter across the face, not strap length.
- Engraving does not change fit — size for wear first, mark second.
