Turn your flask into a tea infuser with this stainless steel infuser basket! These are sized to fit the infuser-compatible bottles. They slide in easily and snap into place so you can infuse on the go. For spa water or other infusions, the top part of the basket can be used without the bottom, leaving you more space in your drink.

Please note that not all of the flasks are infuser-basket compatible, so make sure you double check the listing for the infuser symbol!
