This company was great. My order came missing 1 lid. I contacted them expecting them to just send out the missing lid. They sent out the WHOLE set. Set is made well, they look nice, and I’ve packed my husbands lunch with no spills. Kids are very tight. Sarah. Chapin, SC. Fri Jan 17 2025

Glasslock is made of tempered glass, guaranteeing excellent hardness and durability in comparison with general glass and has an absolute airtight function keeping the liquid, moisture and smell inside. There is no trace of harmful environmental hormones to the human body when using microwave ovens. These clear, stain proof glass containers feature a space saving design. Durable silicone seal provides airtight and leak proof storage. It is ideal for serving and storing, and safe for microwave cooking. Glass lock is BPA free! The plastic in most food containers have BPA chemicals that when microwaved, the food ingests the BPA chemical, not good! These clear, stain proof glass containers feature a space saving, nesting design. All natural glass vessels with airtight lids.
