Adeegsiga tuubooyinka birta birta

Tuubbada gibinta birta waa shey dhuumaha oo caadi ah oo si caadi ah loo isticmaalo, oo loo isticmaalo warshadaha, ilaaliyaha biyaha, dhismaha, ilaalinta dabka, iyo beeraha kale. Waxay leedahay iska caabbinta suuxdinta wanaagsan waxayna xirtay iska caabbinta, waxayna leedahay awood gaar ah.

Tuubbooyinka lugaha birta ah ayaa badanaa laga sameeyaa bir aan la taaban karin sidaa darteedna waxay leeyihiin iska caabin hufan oo wanaagsan. Intaas waxaa sii dheer, biibiile birta birta ah ayaa sidoo kale leh awood aad u badan waxayna u adkeysan kartaa qadar gaar ah oo cadaadis ah. Intaas waxaa sii dheer, tuubbada birta birta ah waxay sidoo kale xidhaan iska caabbinta waxaana loo isticmaali karaa waqti dheer.
