The molded pulp glasses packaging demonstrates how sustainable materials can match the protective performance of traditional velvet-lined cases. Dense fiber compression creates smooth interior surfaces that won't scratch anti-reflective coatings or polarized lens treatments, while the material's natural cushioning absorbs impacts that would crack rigid plastic alternatives. The lid's precise fitment creates a friction seal that resists accidental opening during bag transport, yet releases smoothly without requiring thumb pressure that could transfer fingerprints to cleaned lenses. Ventilation channels molded into the base prevent moisture accumulation from humid environments or cleaning solution residue, protecting metal frames from oxidation and acetate materials from warping.
