Welcome to Tyeign! We select all kinds of high-quality kitchen supplies and everyday tools and home decorations for you.

Reliable Leak Proof Performance: These silicone seal rings create an airtight barrier that stops every drop, so you can toss your bottle in a gym bag or clip it to a backpack without finding a wet surprise at the end of the day. The precision fit means no more sticky spills on car seats, office papers, or camping gear.
Food Grade Soft Flex Material: Made from BPA free silicone that feels smooth to the touch yet resists tearing, stretching, or taking on odors after months of daily use. The material stays pliable from freezing 14 F (-10 C) to steaming 212 F (100 C), so it keeps its shape in hot dishwashers or icy hiking trips.
Six Pack Full Size Range: You receive six rings measuring 1.2 in (30 mm) outer diameter and 0.9 in (23 mm) inner diameter, weighing only 0.3 oz (9 g) each, the same size used on most wide mouth sport and travel bottles. Having half a dozen on hand means you can refresh every bottle in the house or share with teammates and coworkers.
Quick No Tool Installation: Simply stretch the ring around the bottle neck or cap groove and press into place, no screwdrivers, heat guns, or awkward twisting required. The flexible lip seats itself evenly in seconds, so you are back to drinking, not fiddling with tiny parts.
Repeat Wash Economy: Unlike foam or rubber gaskets that crack after a few cleaning cycles, these rings pop out for a thorough wash, air dry, and snap back in looking like new. One inexpensive six pack can outlast dozens of disposable bottles, saving money and keeping plastic out of landfills.
