Lid pieces are not sold separately. When we sold the silicone and slider separately, they often got lost or damaged in transit, so we only sell lids in one full piece.
You can find replacement accessories on this page by clicking on the product image of the item you own to order the correct size. See the image below for an example!
If you'd like assistance choosing the correct accessory please reach out to us at email@example.com with an image of your product and which accessory you need and we'd be happy to help!
