Yog tias koj xav tau txhuam qee cov khoom siv hlau uas siv tsis tau, tshwj xeeb ntawm cov hniav nyiaj hniav kub me me, tom qab ntawd txhuam nrog ntoo tsuav ntoo (linden, birch, aspen). Txiav cov pas rau daim duab zoo li no uas haum rau thaj chaw uas yuav tsum tau kho nrog cylindrical, lub voos plaub ceg, ntu voos, nrog rau cov haujlwm ua haujlwm uas muaj concave thiab convex. Tshiav qhov no ntawm cov pas nrog cov pasta npaj.
