Ball 1 Piece Sip and Straw Lids include a band attached to the lid, so even consumers who may not have bands at home can drink with ease! There are also rings around our straws to prevent the straws from being pulled out of the lid while in use. Lids fit perfectly on any Regular Mouth (70mm) Ball mason jar. High quality reusable straws are wide enough for thick drinks such as smoothies. Easy-sip opening allows enjoyment with or without the straw. Translucent lid and straw have a more modern and elegant design. Lids and Straws are BPA-free and dishwasher safe. Jars sold separately. Retail package includes two Sip and Straw 1-piece Lids and two reusable straws.
