The ecotanka Bamboo & Stainless Steel Lid is designed to fit three specific cup sizes — each requiring its own custom silicone seal for a snug, leak-proof fit.
To support your commitment to reuse and sustainability, ecotanka provides one replacement lid seal free of charge. (Postage not included.)
This small replacement makes a big difference — extending the life of your cup, reducing waste, and helping protect our planet.
Product: 1 x Replacement BSL-01S Seal (for ChillMate 350ml S Cup Lid)
