This lightsaber lets young Jedi swap 10 coloured kyber crystals in and out of the hilt to customise their blade. Place 2 crystals inside and the colours change. The top crystal lights up the blade and the bottom one lights up the hilt. There are 7 different blade colours and over 50 combinations to try. The blade flicks open and extends when it's time for action. The Force blast effect attaches to the blade for dramatic duels. Sound effects play as you move, and they change depending on which crystals you've chosen. The translucent core glows when the lightsaber is switched on.

The set includes 10 kyber crystals, an extendable blade, Force blast effect, cap, cover and electronic core. Kids assemble the pieces themselves to build their own lightsaber. The design is inspired by the Star Wars galaxy. Comes with 3 AAA batteries included, so it's ready to use straight away. The crystals glow when inserted into the hilt. Suitable for ages 4 years and over.
