Lilac St. Eternal Bond Lash Cluster Glue — Waterproof Black, Brush-Tip Precision, Quick-Tack

This lash glue—previously branded as PRO Lash Glue—combines strong hold with flexible wear so falsies stay in place without feeling stiff. It dries dark to blend with black lash bands and melts away any visible seam, while a brush-tip applicator allows targeted placement for small cluster sections or full-strip lashes. The formula is compact in a 0.16 fl oz tube and has been recognized among notable eyelash adhesives for performance and reliability.

How quickly does Eternal Bond set, and can I adjust lash placement?

The formula is engineered for a fast tack so lashes adhere quickly, yet it leaves a short workable window for small repositioning. This helps when aligning multiple clusters or refining the angle of a strip lash before the glue fully sets. Avoid heavy re-adjusting after the initial bond because repositioning can weaken hold.

• Quick-tack formula for fast application
• Short repositioning window for precise placement
• Brush tip enables controlled glue amounts
• Ideal for both cluster and strip lashes

Will the glue show on my lash line or irritate sensitive eyes?

Once dry, Eternal Bond becomes virtually invisible and helps conceal lash band edges, especially with black lashes. The flexible finish minimizes stiffness that can tug at the eyelid; however, as with any cosmetic adhesive, perform a patch test if you have very sensitive skin or known adhesive reactions. Discontinue use if you experience irritation.

• Dries dark to blend with black lash bands
• Flexible finish reduces pulling sensation
• Patch-test recommended for sensitive skin
• Not formulated as a medical product

How do I use the brush tip for cluster and strip lashes?

The tapered brush applicator delivers a fine, even line of glue for precise placement along a strip lash or a tiny dot on the base of a cluster. For strips, run a thin line along the band and wait a few seconds until tacky; for clusters, place small amounts where each group will sit. The brush reduces waste and helps avoid excess glue that can interfere with a natural finish.

• Use the brush for thin, controlled lines on strip lashes
• Apply small dots for individual clusters
• Allow glue to become tacky briefly before applying lashes
• Store upright with cap closed to preserve brush integrity

How long does the hold last and is it waterproof?

Eternal Bond is formulated to provide long-lasting wear suitable for day-to-night use and holds up against light moisture and humidity. The waterproof properties protect the bond from sweat and minor exposure to water, though not intended for heavy water submersion or extended swimming. Proper application and a clean lash band help maximize longevity.

• Designed for extended wear throughout the day
• Water-resistant formulation for resilience against moisture
• Best longevity when applied to clean, oil-free bands
• Not recommended for prolonged underwater use
