FlutterHabit Underlash Extensions 6 Pair 11–13mm Black — Medium-Volume Reusable Clusters

FlutterHabit Sweetheart prepTECH Classic underlash extensions are petite, pre-cut lash clusters designed to be applied beneath your natural lashes for a natural curl and medium-volume doll-eye finish.

These underlash clusters come as six reusable pairs in Black, ranging from 11 to 13 mm to add subtle lift and definition without the weight of full strip lashes. Made as lightweight segmented pieces, they sit underneath the lash line for a seamless, integrated appearance that complements everyday and special-occasion makeup. Adhesive is required and sold separately; with careful application and maintenance, each wear can last up to ten days.

How do these underlash extensions change the look of my eyes?

The Sweetheart prepTECH clusters add targeted fullness beneath your natural lashes, creating a doll-eye silhouette and gentle curl without overwhelming your natural lashes. Because they sit under the lash line, they close gaps and enhance the lower lash area discreetly.

• 11–13 mm lengths for a graduated, natural effect
• Medium volume clusters to avoid heaviness
• Pre-cut segments for even placement and symmetry
• Designed to blend under the lash line for a soft definition

What is the best way to apply these underlash clusters at home?

Apply with a thin, flexible lash adhesive and a pair of fine-tipped tweezers or an applicator for controlled placement. Gently press each segment beneath your natural lash base, starting from the outer corner and working inward to build the desired density.

• Use a small dot of adhesive on the cluster base—adhesive sold separately
• Place segments beneath natural lashes, not on the waterline
• Hold briefly until adhesive sets for secure placement
• Trim or layer clusters for a custom doll-eye shape

How long do they last and how should I care for them?

With gentle handling and proper cleaning, each set can be reused over multiple wears and individual wears can last up to about ten days. Avoid oil-based products around the eye area and remove the clusters carefully to maintain shape and longevity.

• Clean adhesive residue with a lint-free applicator and alcohol-free cleanser
• Store on the tray to maintain curve and prevent tangles
• Avoid rubbing eyes and oil-based makeup removers
• Replace adhesive each application for best security

Are these underlash clusters suitable for first-time users?

Yes — the pre-cut, lightweight segments are beginner-friendly and reduce the trial-and-error of trimming strips. Start with a few outer segments and increase density as you gain confidence, keeping adhesive minimal for easier repositioning.

• Small segments simplify placement compared with full strips
• Clear instructions and short lengths minimize bulk
• Works well for daily wear and event looks
• Pairs are reusable with proper cleaning and storage
