Finish off any ninja costume for kids in seconds with this 7-piece toy weapons set — two 56cm katana swords, two sai daggers, two shuriken throwing stars and an adjustable back harness that holds both swords in place and leaves both hands free.
Every piece is moulded from lightweight plastic with rounded edges, so children can run, pose and play comfortably right through a Book Week parade or a Halloween party. Wear it over a black ninja suit, a samurai robe or just dark everyday clothes — the harness does the work and the whole look comes together instantly.

Why Parents Choose This Ninja Weapons Set
- Seven pieces in one pack — no hunting down individual swords and stars the night before Book Week.
- Hands-free carry — the twin-sword back harness is the detail that makes a ninja costume look properly finished in photos.
- Lightweight and rounded — plastic construction with smoothed edges, made for costume play rather than combat.
- Works with what you already own — pair it with any black outfit and you have a complete ninja or samurai look.
- Reusable year after year — sturdy enough to go from Book Week to Halloween to birthday parties.
Fabric & Care
Weapons and accessories are moulded plastic; the harness uses polyester webbing with an adjustable buckle. Wipe the plastic pieces clean with a damp cloth and mild detergent. Spot clean the harness webbing in cold water and hang to dry. Do not bleach, do not machine wash, and store flat or hanging in a cool dry place so the blades stay straight.
Book Week and Dress-Up Ideas
For a classic ninja, go head-to-toe black — long-sleeve top, track pants, a black scarf wrapped as a mask — then add the harness and twin katana across the back. For a samurai warrior, swap to a red or navy robe-style top with a wide sash and carry one katana at the hip. For a ninja clan look, let siblings or friends each take a different weapon: one with the swords, one with the sai, one with the shuriken. The set also works brilliantly for stage productions, martial-arts-themed birthday parties, school performances and everyday backyard adventures.
Frequently Asked Questions
Is the costume included with this set?
No — this is an accessory set only. The clothing shown in the photos is not included, which is what keeps the price down and lets you pair the weapons with an outfit you already own.
What age is this suitable for?
Recommended for children aged 4 years and above. It is not suitable for children under 3 due to small parts, and adult supervision is recommended during play.
Are the swords sharp or hard?
No. Every piece is lightweight plastic with rounded edges and tips, designed for costume use and imaginative play only — not for contact.
Will the harness fit an older child?
Yes. The shoulder straps adjust across a wide range, so it fits comfortably from around age 4 through to early high school, and sits neatly over a costume or uniform.
Can I order this in time for Book Week?
Yes. We dispatch quickly from within Australia, so ordering ahead of the mid-August Book Week rush gives you plenty of buffer.

We ship Australia-wide with fast, tracked delivery to Sydney, Melbourne, Brisbane, Perth, Adelaide, Hobart, Canberra and Darwin, plus every regional town in between.
