A customization set that let you upgrade your Bandai Hyper Yo-Yo Woodbullet to a Metalbullet. The Woodbullet and Metalbullet were the Duncan ProYo licensed and rebranded by Bandai.
By removing the wooden axle from the Woodbullet, and exchanging it with the included spacers and bearing, you could effectively upgrade your fixed axle yo-yo to a high-performance ball bearing Metalbullet. This modification was quick, easy, and inexpensive.
You could also reverse the side caps and use the included side cap stickers to create a unique custom-colored version for yourself.
Upgrade kit included the following:
1x - Size A ball bearing axle
2x - Metal spacers
2x - Friction stickers
2x - Side cap stickers
1x - Trick sheet (Japanese only)
