{"type":"firestarter.listing","listing":{"id":"lst_-1HEnJXA","product_name":"Charcoal windowpane linen fitted sheet","category":"Linen Sheets","description":"The Charcoal Windowpane Linen Fitted Sheet by MagicLinen blends modern design with lasting European craftsmanship. Made from 100% European flax linen and certified under OEKO-TEX® Standard 100 (2019OK0776), it’s safe, breathable, and naturally temperature-regulating. The mid-weight 190 gsm fabric is stone-washed for instant softness and long-lasting comfort, with a subtle windowpane pattern adding a refined touch. Elastic edges ensure a secure fit, available in regular and deep pocket sizes, while the fabric grows softer over time handcrafted in Lithuania for effortless, timeless sleep comfort.\nSizing &amp; Fit Available in standard U.S., U.K., E.U., and Australian sizes, with two mattress-depth options: regular (10 in / 25 cm) and deep pocket (18 in / 46 cm). Continuous elastic edging ensures a snug fit that prevents slipping or bunching. For best results, measure your mattress height before selecting your depth. Custom sizing is also available for unique dimensions—contact team@magiclinen.com for a personalized quote.\nCare &amp; Longevity Linen fibers are exceptionally strong and long-lasting, becoming softer over decades of use. Machine wash cold on a gentle cycle with mild detergent and air dry or tumble dry low. The sheet will soften with each wash while maintaining its strength and texture. Its naturally breathable weave prevents moisture buildup, supporting clean, healthy sleep. Pair with our matching natural linen flat sheet, duvet cover, or pillowcases to create a complete, calming bedroom set.\nLast updated October 2025 by MagicLinen.","images":["https://cdn.shopify.com/s/files/1/0640/8454/1699/files/fitted-sheed-charcoal-windowpane.jpg?v=1762256084","https://cdn.shopify.com/s/files/1/0640/8454/1699/files/Charcoal-windowpane-linen-bedding-set-5.jpg?v=1762256084"],"price":123,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:37.314Z"},"share_url":"https://firestarter.network/l/lst_-1HEnJXA","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
