The 12oz size suits toddlers and young kids moving on from sippy cups, and the vacuum insulated stainless steel body combined with a soft silicone straw makes everyday use and travel easier. Cleaning is straightforward since the lid disassembles and most parts are top-rack dishwasher safe, though the tumbler body is best hand washed.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e12oz capacity:\u003c\/strong\u003e A practical size that holds enough liquid for toddlers without being bulky or hard to handle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e18\/8 stainless steel:\u003c\/strong\u003e Food-grade construction gives the tumbler solid durability and a neutral taste for beverages.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacuum insulation:\u003c\/strong\u003e Keeps drinks cold for up to 10 hours and prevents condensation on the outer wall.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeak-proof silicone straw:\u003c\/strong\u003e The built-in valve lets liquid flow when drinking and stops spills when tipped over.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisassemblable lid:\u003c\/strong\u003e The lid and straw come apart for easy cleaning and most parts are top-rack dishwasher safe.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTravel friendly:\u003c\/strong\u003e Narrow enough to fit many car cup holders and designed for on-the-go use without messy leaks.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe Kelso tumbler is ideal for parents of toddlers who are transitioning away from traditional sippy cups but still need a spill-resistant option for daycare, travel, or everyday use.
