Children explore size, height and order as they stack and fit the curved pieces, turning abstract ideas into concrete play. Encourage counting, comparing and pattern-making by asking open questions while your child plays.

Made from chemical free rubberwood with formaldehyde free glue, organic pigments and water based dyes, the set supports safer, more sustainable play. The natural wood tones and gentle colors make it an attractive learning toy at home or school.

Rounded shapes and a smooth finish let little hands handle pieces easily, supporting fine motor development. Pieces are sized to manipulate, sort and stack without small loose parts.
Choose blocks that match your childs skill level, your storage needs, and your values for safety and sustainability.
- Match the Skill: Pick sets that encourage the skills your child is practicing, like stacking, sorting and patterning, rather than just copying shapes.
- Open Ended Play: Look for pieces that combine in multiple ways, so a single set grows with your child and sparks creativity.
- Check Materials: Prefer solid wood with non toxic finishes and formaldehyde free glue, especially for toys that will be mouthed or heavily handled.
- Size and Storage: Consider how many pieces you want to keep out at once, and choose sets that fit your usual play surface and storage options.
- Pairing Ideas: Use simple prompts like sorting by color, building concentric circles, or counting pieces to boost language and math talk.
What exactly is included in the set?
The set includes one cylinder and nine curve blocks in four different colors, designed to form concentric circles.
Are the paints and glues safe for kids?
Yes, PlanToys uses organic pigments, water based dyes and formaldehyde free glue, reducing exposure to harsh chemicals.
How should I clean these wooden pieces?
Wipe with a damp cloth and mild soap if needed, then dry thoroughly; avoid soaking or harsh chemicals to protect the finish.
When is this toy appropriate for my child?
This set works best when a child is practicing stacking, sorting and simple patterning; supervise play and offer challenges that match their skill level.
What are your shipping and return policies?
We ship from a US warehouse, offer free US shipping on orders over $100, and accept returns within 30 days with human customer support available.
