What goes into every frame

Material.
By intention.

Every component in a Guad Amano frame is chosen for how it performs over time — not how it photographs.

The foundation

Cellulose acetate.
A material with memory.

Unlike injection-moulded plastic, cellulose acetate is cut from solid sheets — a slower process that produces frames with genuine depth of colour and a warmth synthetic materials cannot replicate.

It is plant-derived, hypoallergenic, and develops a subtle patina with wear. The frames you buy today will look better in five years than they did on day one.

That is not a claim you can make about most eyewear.

Premium Cellulose Acetate Plant-derived · Hypoallergenic

Three components.
Each chosen with intention.

Frame body

Cellulose Acetate

Plant-derived sheet material. Cut and shaped, never moulded. Depth of colour that injection plastic cannot achieve. Warm to wear, hypoallergenic, develops patina over time.

Origin: Italy & Japan · Grade: Premium optical
Lenses

UV400 Protection

Blocks 100% of UVA and UVB radiation. Scratch-resistant coating as standard. Optically clear base with no colour distortion. Seated and sealed by hand.

Protection: UV400 · Coating: Scratch-resistant
Hardware

Barrel Hinge

Spring-loaded, calibrated open and close. Tested for longevity before fitting. The detail that separates a frame worn for one season from one worn for a decade.

Type: Spring barrel · Tested: 10,000+ cycles
Why it matters

Acetate vs.
everything else.

Most eyewear at this price point uses injected plastic. It is cheaper to produce, faster to colour, and easier to scale. It is also noticeably lighter in the hand, less durable over time, and uniform in a way that reads as cheap up close.

Cellulose acetate takes longer. It costs more. The colour runs all the way through the material, so scratches don’t show white. The surface has tactile warmth. The frame holds its shape.

We use it because it is better, not because it is easy.
