Sanrei Glove

The is a powerful Quincy item.

Training Usage
A Quincy's power can be significantly enhanced using the Sanrei Glove. First of all, a Quincy needs to complete a week of intense training in order to be able to use the glove. The glove operates by repelling spirit particles, making it far more difficult for the Quincy to summon their bow. Any Quincy who is able to successfully utilize their powers while wearing the glove can thus reach much higher levels of power; Soken Ishida referred to it as the "peak of Quincy power." This training is also the basis for the Quincy final form, which may have been what Soken was referring to.

Removing the Glove
It is possible to remove the Sanrei Glove, but this is done only as a last resort,when the user is facing an opponent beyond their current level of strength. It was only shown once during Uryu Ishida's fight against Mayuri Kurotsuchi. The glove completely dissipates after removal, since the user is going beyond their limits as a Quincy.

Recovery
The only way for a Quincy to regain their powers after using the final form is to first exhaust themselves both mentally and physically, then be hit exactly 19 mm to the right of their heart with a spirit arrow. After this, a pentacle-shaped scar will form on the point of impact, and their powers will be restored.
