Are you a kids party activity kit manufacturer?

Yes. K&M manufactures kids party activity kits for OEM, ODM and OBM projects, including dig eggs, craft sets, countdown calendars and group games. Our team can take the project from design and sampling through production, QC, packing and export.

What party kit styles can you develop?

We develop dig egg party kits, dinosaur excavation sets, gemstone digs, marbling and painting kits, wooden magnet sets, rock collection games, countdown calendars and party favor packs. You can source a single item or build a broader range.

Can we customize the contents, packaging and branding?

Yes. We can change the contents, theme, colours, tools, difficulty, languages, box, tray, labels, logo, barcode and warning information. Many buyers start with one of our existing kits and customise it; full new development is also available.

For an existing design with your logo, MOQ starts at 200–500 units per SKU. Custom packaging is usually 500–1,000 units, while new ODM tooling starts around 1,000–5,000 units. Production takes about 20–45 days after approval.

Can you support safety testing for our market?
