The 2-1/4 inch unassembled wooden yo-yo kit features two kiln-dried birch discs, a fixed 3/8 inch wooden axle, and a 44-inch cotton string.

Suggested Uses

This unassembled yo-yo kit is ideal for educational projects on rotational motion and STEM demonstrations, as well as group craft activities where each participant customizes their own design. It's especially popular for kids’ DIY painting workshops, scout badge projects, and summer camp keepsakes. Teachers and crafters use it as a safe and engaging hands-on lesson in basic mechanics or artistic expression. For a unique idea: have each member of a classroom or birthday group decorate both sides differently—one with a personal motif and the other with a class or event theme—then use the completed yo-yos in a group art display before play.

Frequently Asked Questions

• Is the kit suitable for all ages?
  The kit is child-safe with supervision, using untreated birch and non-toxic string; small parts may be a choking hazard for children under 3.

• Can I paint or burn designs before assembling?
  Yes, it's best to decorate discs before assembling for the cleanest finish.

  Yes, the kit is sold individually and in economical bulk packs for groups and businesses.
• What finishes are recommended for child safety?
  Water-based paints and sealers or food-grade mineral oils are recommended for decorative finishes.
