Achieving a discreet, flat installation while maintaining visible fullness is a key requirement when selecting Flat Weft Hair Extensions. However, the available product information does not provide a verified weft thickness, density rating, or weight-per-weft figure. For that reason, an exact thickness cannot be recommended as a confirmed solution without reviewing a physical sample or receiving written specifications from the supplier.
Flat Weft Hair Extensions are part of the broader Meir hair extension range. The company offers several attachment and weft systems, including Flat Weft, Hand-Tied Weft, Genius Weft, Tape-Ins, Clip-Ins, I Tip, U Tip, Flat Tip, Plastic Tip, and Nano Ring Hair.
A flat fit is determined by more than the product name. The final result depends on the actual weft construction, material distribution, installation method, hair density, and the amount of hair required for the desired finished style. Since the supplied data does not document these Flat Weft measurements, fullness and profile should be validated before production or bulk ordering.
The current information identifies Flat Weft as an available product type, but it does not state its physical thickness, weft width, grams per bundle, density level, or fullness standard. Without those technical details, there is no reliable basis for naming one thickness that will sit flat and still create adequate coverage.
Meir hair supports customization for color, root color, piano color, balayage color, length, texture, weft construction, and attachment method. These options make it possible to develop a Flat Weft product around a specific salon, wholesale, or private-label requirement. Thickness itself is not listed as a confirmed customization parameter, so it should be discussed directly and included in the approved order specification.
The supplied product record applies to Double Drawn Virgin Chinese Remy Human Hair Tape-In Extensions, rather than Flat Weft Hair Extensions. It describes a natural silky straight wave, customized colors, lengths from 18 to 24 inches, no-tangle and no-shedding characteristics, and a minimum order quantity of one piece.
Stock tape-in orders are listed with delivery within seven days, while customized orders may require 15 to 30 days. Although these details are useful when assessing supplier capabilities, they should not be treated as verified specifications for a Flat Weft product.

For salon professionals, the goal is to select a weft construction that rests close to the natural hair without producing a bulky line, while still supplying the visual density needed for the client’s style. For distributors and private-label brands, this should be handled through a documented sample approval process rather than assumptions based on category names.
Before confirming a Flat Weft Hair Extensions order, request details on weft construction, finished thickness, hair weight, length, texture, color, fullness or density, and the expected appearance after installation. A production sample can confirm whether the extension remains low-profile while delivering sufficient volume.
The company's experience includes supplying customized lace wigs, mono wigs, and other wig constructions in varied colors, lengths, and densities for a European distribution project. It has also provided multiple extension formats, including Machine Weft and Hand-Tied Weft, for professional salons and hairstylists in the United Kingdom. These projects show experience across different hair constructions, but they do not verify a specific Flat Weft thickness.

| Product or Service | Verified Details | Impact on Flat Fit and Fullness |

| Flat Weft Hair Extensions | Included in the product portfolio | Availability is confirmed, but no thickness or density measurement is supplied |
| Tape-In Hair Extensions | Double Drawn Virgin Chinese Remy Human Hair, 18-24 inch lengths | Provides product information for tape-ins only and cannot define Flat Weft performance |

| Quality Inspection | Checks include material, color, texture, shedding, length, weight, workmanship, appearance, and packaging | Useful checkpoints for assessing samples and finished orders |
No exact thickness is supported by the supplied data. The appropriate construction must be established through a sample review and written confirmation of the product specifications.
No. The available record is for Double Drawn Virgin Chinese Remy Human Hair Tape-In Extensions in 18 to 24 inch lengths. Flat Weft appears separately as part of the wider extension portfolio.
Buyers should confirm the weft construction, thickness, weight, density or fullness, length, texture, color, sample result, and quality inspection standards. These details are especially important for OEM, ODM, wholesale, and private-label orders.
There is no validated Flat Weft Hair Extensions thickness in the provided material that can be presented as the universal answer for a flat and full result. The most practical approach is to request a sample, assess the installed appearance, and approve the final weft construction, hair weight, fullness, and profile before starting production.
