The CDN series features a flat braided cotton wick with a special paper filament to promote maximum and consistent capillary action while ensuring a wick trimming flame posture. The difference between Stabilo KST Wick and Stabilo Wick is a subtle but vital one. The Stabilo KST curls less while the Stabilo curls more. Overall, they tend to burn cooler than the CD wicks in most waxes. CDN wicks will curl at approximately a 30-degree angle. The CD wicks curl to a 90-degree angle. The lesser angle or curl of the CDN wick will result in a smaller melt pool or base.
