here is where the quincies keep all their gear for battle such as silver tubes and new bows learn new techniques while here.
The Quincy possess numerous artifacts and equipment which help them in different ways. Below are the ones that have been shown:

Quincy Items:
Hollow bait — This item is a small, coin-shaped disk that attracts hollows when crushed.[8] When used by Uryū, the bait, in combination with Ichigo's powerful spiritual pressure, was able to draw a gillian-class menos out of Hueco Mundo.

Quincy bangle (装身具, sōshingu?) — Introduced in the anime's Bount arc, the Quincy Bangle is an artifact designed to mimic a Quincy's natural powers. It works by drawing in spirit particles from the environment, much like a Quincy does regularly. It can only be used properly by those who are already adept at forming and directing spirit particles. When activated, it forms a metal bow on the user's hand and gives them an appropriate Quincy outfit to match. The bangle is an unstable and delicate device, which eventually falls apart with extended use.[9] The bow it creates has a huge drawback in that spirit particles must be gathered and charged to be of any use; doing otherwise greatly weakens the power of the resultant projectiles. The arrows also seem to fire erratically, sometimes curving away from their intended target. Furthermore, if shot at the time when the device is at its maximum power, it could explode, killing the user and destroying anything else nearby. Uryū was able to bypass most of these problems by using the bow to focus his own suppressed powers, rather than relying on it to draw in spirit particles for him.

Quincy cross (滅却十字, mekkyaku jūji?) — Standard equipment for any Quincy, the Quincy Cross acts as the focus for a Quincy bow. The cross need not necessarily be in a cross shape, as Ryūken's cross is a pentacle.

Sanrei glove (散霊手套, sanrei shutō?) — The sanrei glove is a powerful Quincy artifact that can increase a Quincy's power exponentially, but requires a dangerous and exhausting type of resistance training (wearing it for a week while constantly firing spiritual arrows) to master. The glove works by scattering the spirit particles in the surrounding area, making it much harder to form a working bow. If a Quincy can summon a bow and use it for the required amount of time, they will have undergone a massive increase in power. When removed, however, the glove will release the user's energy all at once - first transforming them into a being of tremendous strength, and then forcing their Quincy powers to gutter out completely.

Seele Schneider (魂を切り裂くもの（ゼーレシュナイダー）, Zēre Shunaidā?, German and Japanese for "soul cutter") — The Seele Schneider is a thin, sword-shaped arrow. It's much longer than a standard arrow and functions something like a chainsaw: the spirit particles of its blade vibrate at ultra-high frequencies, loosening the molecular bonds between any spirit matter it cuts so that the Quincy user may easily absorb the freed spirit particles. The Seele Schneiders Uryū uses are stolen from a secret storage room under Karakura hospital.

Silver tubes (銀筒, gintō?) — Silver tubes are small liquid-filled capsules that store spiritual energy, and are used by Quincy for spellcasting in the same way that shinigami use kidō. Like kidō, they are activated by calling out various commands, but do not require any of the user's energy to activate.

Soul-synthesized silver (霊化銀, reika gin?) — Soul-synthesized silver was used by Ryūken Ishida to construct the hidden chamber in which Uryū trains.

Soul-synthesized glass (霊化硝子, reika gurasu?) — Like soul-synthesized silver, soul-synthesized glass was used to construct the hidden chamber in the Karakura Hospital.

Silver Tube Techniques:
A list of techniques that utilize silver tubes (gintō):
Heizen (聖噬（ハイゼン）, haizen?, German for "to heat," Japanese for "holy bite") — This technique uses four silver tubes to create a transparent, rectangular beam of energy which slices through the opponent.

Gritz (五架縛（グリッツ）, gurittsu?, Japanese for "five-rack binds") — This technique forms a man-sized pentacle symbol which envelops its target.

Wolke (緑杯（ヴォルコール）, vorukōru?, German for "cloud," Japanese for "green goblet") — This technique uses a silver tube to create a large blast. While it may not be intended for use as such, Uryū uses it to cushion the impact of a fall.

Sprenger (破芒陣（シュプレンガー）, shupurengā?, German for "detonator," Japanese for "ripping grass formation") — This technique uses five Seele Schneiders to create a pentagram-shaped seal, which when activated causes a massive explosion within its borders. The Seele Schneiders function as accumulators, gathering the necessary amount of spirit particles to create the explosion. The liquid inside the gintō acts as the trigger. The preparations for the technique combined with the charging time for the Seele Schneiders make its use in battle impractical unless the user has a partner that can stall to buy time.

Quincy Techniques:
To go with their bow, the Quincy have a number of special techniques to give them an edge in combat:
Hirenkyaku (飛廉脚, Hirenkyaku? lit. "flying screen step/god step", "flying bamboo-blind leg" in the Viz translation) — Analogous to the shinigami flash steps or the arrancar sonido, the Quincy hirenkyaku allows the user to move quickly over short distances; according to Uryū Ishida it is faster than flash steps, though Mayuri Kurotsuchi's superior speed suggests that this is just a generalization. To perform the technique, the user gathers spiritual particles under their feet and rides them to the desired location. Like the air-walking skill displayed by most arrancar and shinigami, it can also be used to hover or fly for long distances. Mayuri compliments Uryū on being able to use this technique at such a young age, suggesting that it's difficult to master.

Ransōtengai (乱装天傀, Ransōtengai? lit. "heavenly wild puppet suit", "disheveled paradise puppet" in the Viz translation) — Ransōtengai is a high level technique that allows the user to control their body parts using strings of spirit energy controlled by their brain. By using this technique, the user can control their body as one would a puppet, allowing them to move freely despite paralysis, broken limbs, or any other force that would impede normal movement. It was originally created to allow old Quincy to fight effectively, and is rare enough that Mayuri had never encountered a Quincy (out of the 2661 that he examined or studied) who could use it before Uryū.
