Rainbow Stacking Cups

BPA-Free. Nesting. Bath-Friendly.

Product Overview
The ToyBoom Rainbow Stacking Cups offer endless possibilities for open-ended play. This set of 8 brightly colored cups stacks tall, nests compactly, and doubles as bath toys with their water-play design. Made from BPA-free, food-grade plastic, these cups are safe for teething toddlers and durable enough for years of building, sorting, and splashing. Each cup features a different bottom pattern (star, circle, square, diamond, etc.) for stamping in sand or playdough.

Stack, Nest, and Sort
The cups are sized progressively, allowing children to:

• Stack them from largest to smallest, building a tower up to 22 inches tall

• Nest them inside one another for compact storage and fine motor practice

• Sort by color, size, or number (each cup has a raised number 1-8 on the bottom)

The largest cup measures approximately 4.5 inches tall; the smallest is 1.5 inches.

Bath and Water Play Ready
Each cup has small holes in the bottom, turning them into strainers, sprinklers, and water wheels during bath time. Children can:

• Scoop and pour water between cups

• Watch water stream through the holes like a shower

• Fill and dump, developing hand-eye coordination

The cups dry quickly and resist mold when stored properly.

Safe for Toddlers
The cups are:

• BPA-free, phthalate-free, and lead-free

• Rounded edges with no sharp points

• Dishwasher safe (top rack)

• Teething-safe for babies who mouth toys

The bright, non-toxic colors do not fade or chip with normal use.

Learning Through Play
These cups support early childhood development:

• Fine motor skills: Grasping, stacking, and nesting

• Cognitive skills: Size comparison, color recognition, counting

• Cause and effect: Pouring water, watching cups tumble

• Problem solving: Figuring out which cup fits where

Open-ended design means the play possibilities grow with the child.
