We needed "silk" for a school project using natural dyes and fibers. This is "polyester silk". It was my fault for not checking the reviews and not trusting the ads. A clearer title and description would be great for customers.
Pros
Features: Softly textured and durable, these high-quality handkerchiefs are easy to care for like new, and have a smooth, rich luster that lasts much longer than silk.
