Single vs Double vs W Glue Strip: A B2B Comparison for Pre-Glued Lash Brands
Single Glue Strip uses one adhesive strip at the lash base. Double Glue Strip uses two, and W Glue Strip uses a W-pattern arrangement. QUENLIRA’s selected DIY cluster lash program offers each construction in transparent and black. Compatibility depends on the lash style, and some designs support only Single Glue Strip.
For a private-label order, start with the lash reference. Ask which constructions are available for that style before specifying strip color, packaging or samples.
What is a pre-applied adhesive strip?
It is the adhesive component already applied to the base of a lash cluster. In a conventional DIY cluster system, the user typically applies a separate lash bond. In a pre-glued design, the cluster arrives with adhesive on its base. The lash band or base and the adhesive strip should be recorded separately in the product specification.
Compare the three glue strip constructions
| Construction | What it describes | What to check on a sample |
|---|---|---|
| Single Glue Strip | One pre-applied adhesive strip at the lash base | Check where the strip sits, how the base looks and how the cluster handles when lifted from the tray. Some styles are available only in this construction. |
| Double Glue Strip | Two pre-applied adhesive strips | Check the alignment and distribution of both strips and whether the assembled base fits the selected tray. Confirm availability for the specific style. |
| W Glue Strip | A W-pattern adhesive arrangement | Ask for a close-up of the actual pattern. Check its placement on the base and how the cluster handles during removal from the tray and application. Confirm availability for the specific style. |
Transparent and black are available across all three construction types at the program level. Ask which combinations are available for the individual style. Strip count, pattern and color alone do not establish adhesion strength, wear time, comfort or safety.
Choose the strip color with the lash style
Transparent adhesive can be considered when the brief calls for a less visibly colored base. Black adhesive gives the base a darker appearance. Review both against the intended lash style and band under the same lighting. Confirm the strip color separately from the band and fiber colors.
Confirm the exact configuration before ordering
All cluster styles in the selected program catalog can be developed as pre-glued, including Natural, Wispy, Volume, Cat-Eye, Manga and specialty styles. The program supports length customization from 6–20 mm. Curl, fiber, band, color and mixed-length layouts depend on the selected design and are confirmed during technical review and sample development. See available pre-glued cluster customization options.
- Send the lash reference and target appearance. Include the style, length or length mix, curl, fiber and band requirements.
- Ask which strips are compatible. Request a close-up of each viable construction for the chosen style and confirm the available strip colors.
- Compare like with like. Where feasible, keep the lash style, length, curl, strip color and application conditions consistent so the construction is the main difference.
- Check the retail pack. Evaluate tray fit, cluster removal, condition of the strip after handling and consistency across sampled pieces. Review private-label packaging options with the chosen configuration.
- Approve the production reference. Record the sample ID and revision, lash reference, strip type and color, tray configuration, and agreed acceptance criteria. Use the approved sample and written specification for bulk production and quality review.
Frequently asked questions
Can every catalog style use all three strips?
Every style in this selected catalog can be developed as pre-glued. Some styles support only Single Glue Strip. Ask for the available constructions by style before sampling.
Is Double Glue Strip stronger than Single Glue Strip?
Strip count alone cannot establish stronger adhesion. A performance comparison requires evidence for the specific products and application conditions.
What should I include in a sample request?
Send the lash reference, preferred strip type and color, length or length mix, curl, fiber, band, target market and packaging requirements. If the strip is still undecided, ask which options are compatible with your chosen style.
