Factory Seconds: 3-in-1 Stainless Steel Transition Cup
Same cup, slightly imperfect. Full testing, full function.
We hold our products to a high standard. Sometimes a cup arrives from production with a minor cosmetic mark, a small surface scratch, or tiny dents on the steel cup that mean it does not quite meet our usual presentation bar. The cup itself is perfectly fine. The materials are the same. The leak-proof lids seal the same way. The stainless steel is the same 18/8 food-grade body. It has just earned a discount for looking a little lived-in before it even arrives.
The Leak-Proof Transition Cup for Every Stage
The transition cup that grows with your child. This plastic-free upgrade features a redesigned leak-proof sippy lid for beginners, a leak-proof straw lid paired with a clever valve straw for on-the-go adventures. Designed with oral development in mind, our straw lid supports mature swallowing patterns. Read our guide on why speech pathologists prefer straw cups over hard spouts. When your little one is ready for the final milestone, simply remove the lid to graduate to a big-kid open training cup. One durable, unbreakable cup for every developmental leap.
Classic-Sage Model: This is our previous generation model that has press-on lids and a free-flow straw. This cup is spill-resistant, not leak-proof.
Designed with Development in Mind
Beyond being practical, this cup is designed to support your child's physical growth. Moving from a spout to a straw and eventually to an open cup is a journey that supports healthy oral-motor development. By encouraging the lip and tongue strength needed for clear speech and confident swallowing, we’ve made sure that the "healthy choice" is also the easiest one for parents to make. Not sure when to switch from the spout to the straw? We have summarised the American Academy of Pediatrics (AAP) and Raising Children Network guidelines for you.

Whether it is a morning smoothie or water on the bedside table, this non-toxic sippy cup is a reassuringly sturdy, shatterproof essential that prioritises your child's health and our planet's future.
What "Factory Seconds" Means at Greenvyne
Every factory-second cup has been individually assessed. The imperfections are cosmetic only and vary between cups: a faint surface scratch or minor dents on the steel cup. What you will not find is any compromise to the seal, the 304 stainless steel grade, or the food-grade FDA silicone components.
If you are buying one for home use and one for grandparents. This is a great choice.
Limited stock available: Sage, Peach, Cocoa, Cream and Classic Sage (Classic Model with press-on lids and free-flow straw)
Recommended from 12 Months: Designed for toddlers who are ready to transition from a bottle. At 6–12 months, babies are naturally inclined to pull and push with force. From 12 months, the cup comes into its own as little ones develop more intentional drinking habits.
