25L Four 1920s–30s Czech Uranium Custard Glass Buttons, 5/8"

Vintage 1920s-30s Czech uranium custard glass buttons, set of four.

Each button measures approximately 15.8 mm (25 lignes, 5/8 inch), ideal for cuffs, collars, blouses, or elegant dress details from the 1930s.

Crafted in Jablonec nad Nisou, Bohemia, the historic center of European glass button production, these buttons showcase classic Art Deco sophistication. The opaque white milk glass has a soft, creamy, luminous base, accented by hand-applied alternating silver and gold metallic luster borders.

A hidden delight: these buttons contain uranium oxide and fluoresce a vivid neon chartreuse yellow under blacklight (UV), a signature feature of authentic pre-WWII Czech uranium glass.

Construction is seamless, with a molded self-shank for secure sewing and authentic to the period.

Measure approximately 25L, 25 lignes, 15.8 mm, or 5/8".

This matched set is a rare and magical example of interwar Bohemian artistry, combining streamlined elegance with the distinctive “glow” that uranium glass collectors prize.

They are perfect for collectors of Czech/Bohemian glass, uranium/vaseline glass, Art Deco buttons, vintage fashion restoration, or jewelry projects.
