Matubo™ Rulla N. 12 - Jet

Opaque Jet Black glass offers a sophisticated foundation for precision-engineered bead weaving. These Matubo™ Rulla beads feature a unique 3x5 mm cylindrical shape with two parallel holes, ensuring perfect alignment in geometric patterns. Professionals appreciate the consistent 0.8 mm hole diameter, which allows for multiple thread passes through the bead without risk of structural failure, making them essential jewelry components for complex designs.

• Uniform cylindrical shape for sleek architectural beadwork.
• Dual-hole technology for stable multi-row construction.
• High-quality Czech glass with deep, light-absorbing pigmentation.
• Perfectly calibrated for consistency in mass production jewelry.

The material quality reflects the heritage of the Czech glass industry. While manufactured by Matubo, the glass originates from high-grade Preciosa glass batches, ensuring a durable and glossy finish that resists fading over time. For intricate structures, these act as excellent glass spacers when paired with Preciosa seed beads, providing the necessary articulation and movement in flexible bracelets or necklaces.

Technical tolerances are critical for advanced jewelry design techniques involving high-tension weaves. We recommend using S-lon thread—specifically S-lon D for general use or S-lon FIRE for projects requiring maximum tensile strength—paired with beading needles size 10-12. Considering the total diameter of the needle and doubled thread is essential when planning complex beadwork patterns involving several returns through the same hole.

Achieving a high-contrast aesthetic is effortless with this deep Jet Black finish. For a striking contrast, pair with bright gold or silver elements, or create a sophisticated, harmonious look by combining them with Czech fire polished beads in dark bronze or metallic tones. A 10 g package contains approximately 96 beads, though weight remains the decisive factor for quantity. These 3x5mm beads provide the structural integrity and sleek profile required for modern, layered artisan jewelry.
