Contigo Tea Infuser for all West Loop Thermo Mugs. This stainless steel tea strainer is designed for loose tea or tea bags and is dishwasher safe. The infuser features fine-pored holes to prevent small tea particles from leaking, ensuring a pure tea experience. It fits perfectly into the lid of West Loop thermo mugs, maintaining the mug's 100% leak-proof seal. The infuser allows for effortless on-the-go brewing without spills. Cleaning is easy as both the cup clip and the stainless steel basket are dishwasher safe or can be cleaned by hand. The infuser consists of three parts: a stainless steel container, a clip to attach to the West Loop travel mug lid, and a drip tray for the removed tea insert. It holds 5-7 grams of tea.
