[Powerful Extractor Blade with Tight Seal] Made from durable, high-strength materials, the cross-shaped extractor blade rotates at high speed to efficiently blend ingredients and release nutrients. Designed for quick preparation of smoothies and healthy drinks—ideal for home or on-the-go use. Features a secure sealing ring for leak-resistant performance and long-lasting durability. [Extra 2 Sealing Rings] One sealing ring is pre-installed on the blade assembly for immediate use and optimal leak protection. Two additional sealing rings are included for future replacement. Do not install extra rings during use—only one ring should be used per blade. Before each use, ensure the blade is fully twisted onto the cup until tightly sealed. [Care Instructions] Do not submerge the blade assembly in water. To clean, twist off the blade, wash by hand with warm, soapy water, rinse thoroughly, and air-dry completely. Do not remove the sealing ring—doing so may cause permanent damage and leakage. For best performance, replace the blade every 6 months or as needed.
