This is a replacement lid for a Stanley tumbler. While the straw-only type can leak, switching to this lid prevents spills even when the tumbler is on its side. I'm selling this because I bought a different water bottle and never used this lid. I purchased it on Amazon, advertised as compatible with both 30oz and 40oz Stanleys, but I gave my Stanley tumbler to a friend before I could use it, so I don't have specific details. - Color: White - Material: Stainless steel, plastic - Features: Straw, silicone ring - Included: Straw, lid - Condition: Unused - Retail price: ¥1,600 Please refrain from purchasing if you are overly concerned about minor imperfections, as this item has been stored at home. * Cancellations and returns are not accepted after purchase. Please feel free to ask any questions in the comments ( ¨̮ )
