Imashini imesa isanduku yubatswe cyane cyane mubyuma bidafite ingese, ifite imbaraga zo kwangirika, hejuru - irwanya ubushyuhe, hamwe na okiside. Igumana ituze ryimiterere na nyuma yo kumara igihe kinini ihura namazi, ibikoresho byogajuru, hamwe nibisigazwa byibiribwa . 304 ibyuma bitagira umwanda bikunze gukoreshwa mubice byingenzi; ubuso bwayo bworoshye bugabanya imikurire ya bagiteri kandi bigabanya ibyago byo kwambara no kubora.
Sisitemu yohereza no kohereza ikoresha ibyuma byimbitse kugirango byongere umutwaro - ubushobozi bwo guhangana ningaruka. Ibikoresho byerekana ihinduka rito mugihe gikora kenshi, gifite igihe kirekire cyo kubungabunga, hamwe nubuzima bwa serivisi burengeje imyaka 10. Igishushanyo mbonera cyubatswe muri rusange gifite ishingiro, hamwe nuburyo bukomeye kugirango wirinde kwanduza umwanda no kunoza igihe kirekire. Guhitamo ibikoresho biringaniza imbaraga nibisabwa byisuku, bigatuma bikwiranye n’ibidukikije - ubukana bw’ibidukikije.
