Topper Base Bead = 20mm | Center-Hole Flatback Bead for Pen Toppers
Build dimensional, elevated designs with this 20mm Topper Base Bead, designed specifically for creating custom pen toppers.
This bead features a center-aligned hole orientation, allowing it to screw directly onto standard beadable pen bars and act as a secure foundation for your topper design.
While it uses the same base shape as the traditional flatback bead, the hole orientation is different — making this version ideal for topper builds.
✨ Designed for Topper Builds
• 20mm round flatback surface
• Center hole for direct threading onto pen bars
• Creates a stable topper platform
• Ideal for layered and dimensional designs
This is not a decorative spacer — it is a structural topper base.
