Kids Sublimation Tumbler 12oz 8 Pack - Customizable Insulated Sippy

In this review of the Kids Sublimation Tumbler 8 pack, the bottom line is simple: this set is best for crafters and parents who want fully customizable, insulated sippy cups for children. The pack is aimed at hobbyists who plan to personalize cups using a sublimation process, and the single biggest reason to buy is the high-quality sublimation coating that consistently produces vibrant color transfers. The reviewer found the 12oz size, soft silicone nozzle and handle make these practical daily cups, while the double wall stainless construction provides real temperature performance.

Key Features

• Sublimation coating: The high-quality coating accepts transfers well and produces bright, true-to-design colors for custom artwork.
• 304 stainless steel: Durable, BPA-free construction gives an odorless, non-toxic drinking surface safe for kids.
• Double wall insulation: Vacuum insulation helps keep drinks cold for up to 12 hours and warm for up to 6 hours for everyday use.
• Soft silicone nozzle and pad: The soft nozzle protects a child's mouth and teeth while the silicone bottom pad prevents dents and sliding.
• Spill proof lid with handle: The lid includes a pop-up silicone straw and handle for easy carrying and convenient drinking on the go.
• 12oz straight design: The compact shape fits most cup holders and schoolbag side pockets for simple transport.

Who It's For

This 8 pack is ideal for small business owners, craft hobbyists, teachers, or parents who want to personalize drinkware for children for birthdays, holidays, or classroom gifts. The set size and consistent sublimation finish make it efficient for producing multiple matching or themed cups.

Families who need a single, rugged everyday sippy may want to consider single-brand sealed lids with stronger closures, since some customers report lid durability and seal issues. If ease of replacement parts is a priority, look for cups with proven long-term lid reliability.
