This is a Persian rug imported directly from Iran, woven with an ultra-high density of approximately 2.25 million knots. In Iran, it is sold as a machine-woven version of a Persian rug, and it is a rug of the highest quality rank for machine-woven rugs, a product rarely seen elsewhere. The weaving density of rugs is considered very fine from around 1 million knots, but this rug has an even finer weave, with approximately 2.25 million knots/m², which is more than 2.2 times finer. (The weaving density of commonly available rugs is around 90,000 knots to 750,000 knots.) It has the authentic design of a hand-woven Persian rug, the fineness of a weave exceeding hand-woven rugs, and the durability unique to machine-woven rugs. It is a Wilton weave with a durable and sturdy finish. The fibers are heat-set processed, giving it a texture and feel similar to cork wool. It also has high moisture retention, similar to wool. Furthermore, unlike wool, it does not develop a unique odor over time, nor does it suffer from insect damage or fading like vegetable dyes, allowing you to enjoy its unchanging beauty for a long time. Regular maintenance is sufficient with a vacuum cleaner. If it gets dirty, spot clean with a carpet cleaner, and you can have it cleaned at a cleaning shop as a general carpet. ☆ Size: Approximately 60cm x 90cm Weaving Density: Approximately 2,250,000 knots/m² Country of Origin: Iran Material: 100% Acrylic (Heat-set processed) Wilton Weave Thickness: Approximately 0.8cm ※ We try to display the product colors as close to the actual colors as possible, but it is difficult to display the exact same color due to differences in lighting and monitors. For this blue-green color, the close-up image is closer to the actual color, with a slightly greener hue than the overall image. Due to the nature of the product, the pile-less part of the edge's roll (up to approximately 10mm) may be visible. This is not a defect, so please understand. Also, due to the characteristics of the Wilton weave manufacturing method, adhesive is used on the back, corners, and folded-over parts, and you may often see the adhesive there. This is not an abnormality (defect) and has no effect on the human body.
