Stanley cup friends, I found the best lids for our 40 oz tumblers! These detachable ProTour lids are leakproof, easy to clean, and come with a flip straw that makes life so much easier. Right now, I have a promo code 50ONKMLA to get them for 50% off. That’s $8.75 for a 2-pack! Just had to share because these are a total game changer. LTKHome LTKSaleAlert LTKFindsUnder50
