Zikwama zam'mbali za gusset ndi matumba otchuka kwambiri a khofi ndi tiyi, choncho amatchedwa "matumba a khofi kapena tiyi". Koma pakadali pano ikugwiritsidwanso ntchito pang'onopang'ono kulongedza ufa wa mkaka, mabisiketi, matumba a chakudya cha agalu, zoseweretsa, zida zamankhwala, ndi mafakitale ena.
Matumba am'mbali a gusset amakhala ndi maziko athyathyathya ndipo nthawi zambiri amasindikizidwa popinda pamwamba kapena kutentha kusindikiza pamwamba. Ubwino wogwiritsa ntchito kapangidwe kameneka ndikuti matumbawa nthawi zambiri amakhala owoneka bwino komanso osasunthika, mapangidwe amatha kupita mbali zonse za 4 zazinthu zomwe zimalola makasitomala kuzindikira zomwe zili mu 360 °.
Kukhazikika kwachikwama chapakona kumapangitsa kuti chikhale chowoneka bwino pamashelefu akusitolo.
Matumba am'makona ndi oyenera kulongedza 500g mpaka 20kg, ndipo ndi oyenera kulongedza katundu wamakampani a tiyi ndi khofi kapena kugulitsa zokhwasula-khwasula, chakudya cha ziweto, zakudya zamasewera ndi zinthu zina. Mawonekedwe a quadruple seal amapereka mwayi wogwiritsa ntchito zosindikizidwa zapamwamba kuti muwonjezere zambiri zamalonda ndi zotsatsira. Popeza palibe chisindikizo chakumbuyo, mungapindule ndi chidziwitso chamtundu wopitilira pa mapanelo anayi a thumba, zomwe zikutanthauza zowoneka bwino komanso kuthekera kwamtundu.
