Cat Ear Mug Lid, 100mm Diameter, focusing on materials, specifications, functionality, care and maintenance, and purchasing considerations to help you easily compare and choose:

I. Key Specifications and Materials

1. Standard Dimensions: Outer diameter 100 mm (3.94 inches), compatible with most household mugs and coffee cups (cup opening inner diameter typically 90–98 mm; silicone’s elasticity accommodates minor tolerances); thickness approximately 2–3 mm, with cat ears standing about 10–15 mm tall; single-piece weight 30–40 g.

2. Common Materials: Food-grade silicone (BPA-free), with a temperature range generally from -40°C to 230°C; microwave- and dishwasher-safe (though some designs recommend hand washing); a few models are made of eco-friendly PP material (lighter but less heat-resistant than silicone); metal-free options prevent scratching the cup.

3. Appearance and Color: Circular base with symmetrical three-dimensional cat ears; predominantly solid colors (white, black, pink, blue, orange, gray, etc.), with some designs featuring detachable cat ears for thorough cleaning; the cat ears serve both as decorative accents and convenient handles, remaining cool to the touch when flipped over.
