2. Txhawm rau nthuav dav daim ntawv thov ntau yam ntawm cov ntawv khob, ncaj-phab ntsa ob-txheej ntawv khob tau tsim nyob rau xyoo 1940. Lub khob ntawv no tsis yog yooj yim nqa xwb, tab sis kuj siv tau los tuav cov dej kub.Txij thaum ntawd los, cov tuam txhab lag luam tau coated lub khob nrog latex los npog daim ntawv "dawb tsis hnov tsw" thiab txhim kho lub khob cov khoom pov thawj.Ib-txheej wax khob nrog cov latex txheej yog dav siv los tuav kas fes kub hauv vending machines.
