Choosing a premade fan fiber that feels soft yet maintains its structure requires more than reviewing a material list. This product is offered in Korean PBT fiber, silk, and cashmere, but the available specifications do not identify which option provides the best combination of softness and shape retention. Buyers should request samples or obtain direct technical guidance from the supplier before making a final decision.
The specification lists Korean PBT fiber, silk, and cashmere as available materials. However, it does not include hand-feel evaluations, shape-recovery testing, stiffness measurements, or a performance ranking. As a result, none of the three fibers can be confirmed as the softest option that also holds its fan shape most effectively.
For a dependable comparison, buyers should examine physical samples and ask the supplier about fiber softness, curl stability, fan separation, and resistance to deformation during application. These checks are more useful than selecting a material based solely on its name.
The product uses a narrow premade volume fan format. It is offered in 6D, 8D, 10D, and 20D densities, allowing lash professionals to select the desired level of volume. Curl choices include J, B, C, CC, D, DD, L, L+, M, LC, and LU.
Thickness options include 0.03 mm, 0.05 mm, and 0.07 mm, while available lengths run from 6 mm to 18 mm. Mixed-length sets can also be requested. These configurations help match the fan to different lash styles, but they do not establish that one listed fiber is softer or more shape-stable than another.

Because the supplied data does not compare the tactile and structural performance of the three materials, the most practical approach is to request samples of Korean PBT fiber, silk, and cashmere. Evaluate how soft each sample feels, whether the fan remains evenly spread, and how well the structure survives handling and application.
After the material has been assessed, buyers can select the appropriate density, thickness, curl, and length for their service menu. UBEMAY also supports OEM and ODM development, private-label production, wholesale supply, bulk purchasing, and flexible small-batch orders.
No specific fiber is confirmed by the available product information. Korean PBT fiber, silk, and cashmere are all listed, but comparative softness and shape-retention results are not included.
The product is available as a narrow premade volume fan in 6D, 8D, 10D, and 20D formats. Buyers can also choose among several thicknesses, lengths, and curl styles.
Request samples or technical confirmation from the supplier. Compare softness, fan stability, curl consistency, and handling performance based on the intended lash application.
The current specifications do not justify identifying one material as both the softest and the most capable of retaining its shape. A sample-based comparison of Korean PBT fiber, silk, and cashmere is the most reliable way to make the decision. Once the fiber is selected, the fan density, thickness, curl, and length can be customized for the target application. For product details and technical assistance, contact sales@ubemay.com.
