ʻO ke kiʻi polimer fiber lāʻau ʻohe i hoʻokuʻu ʻia, mānoanoa semi-circular-arc hollow cavity, kaomi ma waena o ka hui ʻana, 25mm mānoanoa, kiʻekiʻe ke kūkulu ʻana i ka ikaika, thermal laminated surface.

ʻO ka hoʻolima ʻana i ka paia, ka pale ʻokiʻoki, ka hoʻonani komo, ke keʻena hōʻikeʻike, hale kūʻai i nā mea hoʻonaninani laina.

ʻO ka hiʻohiʻona semi-circular arc kū hoʻokahi; ʻO ke kiʻekiʻe rigidity 25mm mānoanoa ka ʻaoʻao kūʻē i ka piko; 30 mau ʻāpana no ka pahu pahu no nā papahana nui; Nā ʻano hui like ʻole; ʻAʻole wai a me ka moisture-proof, loaʻa no ka lumi o loko a me ka semi-wehe.
