What Stands Out
Stackable Design
Designed for easy storage, these tumblers stack neatly, making them ideal for small kitchen spaces and travel, promoting organization and convenience for parents and their toddlers.
Insulated Construction
The stainless steel insulation keeps drinks at the desired temperature longer, providing a refreshing experience for kids while ensuring parents can rely on durable, high-quality materials.
Safety First
BPA-free lids and silicone straws ensure safety and health for your child, providing parents peace of mind while their toddlers enjoy their favorite drinks without worry.

CUPKIN Tumblers CK-8OZ Editorial Review
The CUPKIN Trainer Sippy Cup set, featuring two 8 oz stackable stainless steel tumblers, is designed for kids and features BPA-free, reusable silicone straws and leak-proof lids.

The review section was mixed, with some customers praising the durability and ease of cleaning while others criticized the product's alleged high lead levels, poor sealing, and overall quality.
