Choosing a premade fan fiber that feels soft and maintains its structure requires more than the material name alone. This product is offered in Korean PBT fiber, silk, and cashmere, but the available specifications do not include tactile evaluations or shape-retention test results. As a result, no single option can be identified as the confirmed best choice without reviewing samples or consulting the supplier.
The specification lists Korean PBT fiber, silk, and cashmere as possible materials. However, it does not state which material offers the softest feel, the strongest curl memory, or the most reliable fan stability. There are also no comparative laboratory results, hand-feel ratings, or long-term shape-retention claims. Buyers should therefore request samples or obtain direct technical guidance before placing an order based on softness and structure.
The premade fans use a narrow volume design and are available in 6D, 8D, 10D, and 20D formats. Curl choices include J, B, C, CC, D, DD, L, L+, M, LC, and LU. These choices help lash artists match the fan density and curl to different styling needs, but they do not prove that one listed fiber is softer or more stable than the others.
Additional specifications include 0.03 mm, 0.05 mm, and 0.07 mm thicknesses, along with lengths from 6 mm through 18 mm. Mixed-length trays are also available. These configuration details affect application and design flexibility, while the actual softness and ability to preserve the fan shape still require material-level verification.

Because softness and shape stability can vary according to production methods and individual preferences, the most reliable approach is to compare physical samples. Evaluate how each fiber feels during handling, whether the fan opens consistently, and how well it keeps its intended shape during application. Supplier confirmation should also cover the expected curl memory, finish, and performance after storage and use.
No. The available information names Korean PBT fiber, silk, and cashmere, but it does not identify a winning material or provide test data comparing softness with shape retention.
The product is available in 6D, 8D, 10D, and 20D narrow volume fans. Customers can also select from 0.03 mm, 0.05 mm, and 0.07 mm thicknesses, plus multiple lengths and curl patterns.
Request samples from the supplier and assess tactile softness, fan consistency, curl recovery, and shape stability for the intended lash technique. Direct technical confirmation can help clarify differences that are not shown in the product listing.
The current product data cannot verify that Korean PBT fiber, silk, or cashmere is the softest option while also retaining its shape. A sample-based comparison is the appropriate next step. Once the preferred material is confirmed, buyers can select the required density, thickness, curl, and length.
