Material: Polyester - Polyester resin became the dominant button material post-WWII due to its affordability, durability, and ability to mimic luxury naturals like tortoiseshell without shortages or regulations.

Uses: Four-hole sew-through buttons are well suited to heavier garments where strength and balance matter. They are a classic choice for men’s suit jackets, blazers, sport coats, or overcoats, whether used on front closures or cuffs. They also complement women’s tailored coats, dresses, or cardigans, adding a refined tortoiseshell-style accent. For outerwear or uniforms, these buttons offer durability with understated elegance - the mottled pattern adds visual interest without being flashy and blends easily with earth tones or darker fabrics. The four-hole design allows for a secure attachment, making them ideal for garments that see frequent wear and use.
