BPA-Free with Silicone Seal: These replacement lids are BPA-free and feature a silicone seal, giving you a secure, leak-resistant fit that keeps your food fresh and your storage worry-free. Correct Size & Fit: This is the replacement lid for the large 1040 ml glass base from the GOOD FOR YOU 10-Pack—ideal if your original lid is lost or damaged and needs replacing. Easy Care, Long-Lasting: For maximum longevity we recommend hand washing. If you prefer the dishwasher, place the lids on the top shelf, as the heating element is usually located at the bottom. Remove the Lid Before Microwaving: These lids don't have a steam vent, so always take the lid off before microwaving. A tightly sealed lid traps steam and pressure, which can warp it over time and weaken its leak-proof seal — removing it keeps the lid in top condition for longer. Brand Compatibility: Like the glass base, these lids are designed specifically for the GOOD FOR YOU 10-Pack and may not be suitable for use with other brands or models. Please check compatibility before purchasing.
