At Four Seasons, every button is made to last. We perform strict quality tests to ensure durability, safety, and international compliance — trusted by fashion brands and garment manufacturers worldwide.
Every button is examined by trained staff for surface defects, color variation, and finish consistency.
We conduct random sampling to check dimensions, strength, and uniformity across production lots.
Where required, we test for durability, wash resistance, and fastening strength based on end-use applications.
Upon request, we coordinate third-party tests (e.g. Intertek, Kaken, Bureau Veritas) to meet international compliance standards.
Every order is reviewed again before leaving our facility to ensure it meets our standards — and yours.

Simulates pressure or force applied during wear or washing to check if the button cracks, chips, or breaks. Essential for ensuring long-term durability.

In addition to our in-house quality tests, we support clients who require compliance with international regulations and third-party certifications. These are often needed by brands, importers, or buyers operating in regulated markets.
