PopTop: Sealable Drinking Jar Lid - Wide-Mouth

PopTops are non-reactive and can be used with hot or cold beverages without any worry of chemical leach. The wide hole is ideal for easy sipping, pouring and storing. The plug is attached to a silicone band that slides over the jar, so you won't lose it. There is a small notch in the silicone band that is designed to hold a straw, so you can have it with you when you need it.
