6 Pack Sublimation Blanks Sippy Cup Baby Bottle 12 oz - Grows

In this review the 6 pack sublimation sippy cups are judged as a versatile starter cup set that transitions from baby sippy use to a regular straw tumbler, making them useful for families who want a single cup design that adapts over time. The most compelling reason to buy is the combination of a true sublimation-ready coating and 18/8 stainless steel construction, which delivers bright custom prints and a durable, rust-resistant body that holds temperature well for everyday use.

Key Features

• Growing design: Starts as a sippy cup and converts into a regular straw tumbler so the same cup can be used as children develop.
• Sublimation coating: A quality sublimation-friendly surface produces vibrant, sharp prints that do not look foggy after decoration.
• Stainless steel material: Made from food-grade 18/8 304 stainless steel so the cup is rust resistant and built to last.
• Insulated performance: Double wall vacuum insulation keeps cold drinks chilled for up to 12 hours and hot drinks warm for over 6 hours.
• Splash-proof lids: Each cup ships with a transparent lid and gasket plus an alternate straw lid, helping keep beverages cleaner outdoors.
• Packaged individually: The six cups arrive boxed separately, convenient for gifting or selling individually.

Who It's For

The set is best for parents, small-business crafters, and hobbyists who want an affordable, sublimation-ready blank that functions as both a child sippy and an adult-style skinny tumbler. Small shops or makers will appreciate the consistent coating and 12 oz size that suits custom designs and gifts.

It is less well suited for users who need a fully leakproof travel cup or a very small toddler spout; a handful of customers reported leaking with the spout under certain conditions, so anyone who needs guaranteed leak protection for long trips should consider a cup with a locking lid system instead.

Pros & Cons
