Lashify Gossamer Bold 12mm DIY Eyelash Extensions Refill — Black, Thicker Mascara-Like Volume

Lashify Bold 12mm Gossamer refills are individual DIY eyelash extension cartridges designed to build fuller, mascara-like volume without traditional strip lashes.

These Gossamer lashes are part of Lashify's patented at-home system and offer a thicker fiber for a bolder yet natural finish. Sold in black and sized at 12mm, the refill cartridge contains multiple lightweight clusters that layer smoothly over natural lashes when applied with Lashify’s recommended tools and adhesive. Made from premium Korean PBT silk and produced cruelty-free, this option suits anyone seeking a customizable, reusable lash routine that avoids heavy glued strips.

How do these 12mm Gossamer lashes change my natural look?

The Bold 12mm length delivers visible lift and density while maintaining a believable lash line. Because the fibers are slightly thicker than the Core Collection, they mimic the effect of volumizing mascara without clumping. Their lightweight construction keeps the lashes comfortable and allows you to build intensity in sections.

• Produces a fuller, mascara-like volume without appearing artificial
• 12mm offers medium length suited for most eye shapes
• Thicker fibers add definition for a slightly dramatic yet natural finish
• Layerable design lets you control coverage and shape

What tools and steps are needed to apply Gossamer lashes correctly?

Gossamer lashes are engineered for use with Lashify’s patented tools — not standard tweezers or applicators. For best adhesion and placement, use the Fuse Control Wand along with the brand’s adhesive formulas and follow the recommended technique to seat the fibers on top of your natural lashes. Proper technique reduces handling damage and ensures a long-lasting bond.

• Use the Fuse Control Wand for precise placement and pressure control
• Apply with Lashify adhesive formulas designed for the system
• Avoid regular tweezers to prevent misshaping the fanned clusters
• Allow the bond to set before contact with water for optimal hold

How should I care for my Gossamer lashes to extend wear and safety?

After application, keep the lashes dry for at least 12–24 hours to let the adhesive fully set. Clean gently around the lash line, avoid oil-based removers, and handle clusters carefully when removing or repositioning. With proper aftercare and use of the Lashify system, you can maintain a clean, comfortable lash line and reuse accessories safely.

• Do not wet lashes for a minimum of 12–24 hours post-application
• Avoid oil-based cleansers that can weaken the bond
• Gently remove using Lashify-safe remover or recommended technique
• Store unused cartridges away from heat and direct sunlight
