This brand was established since 1628 in China. Compared to other expensive brands, it is good alternative. I highly recommend this brand because I also use one of their low level shears.
Yes, it is heavy not plastic and it can last way longer time than plastic ones.
They use 65Mn SP manganese steel instead of ordinary steel, so the shears are very strong and sharp.
This high level pair of scissors is not available outside China yet (there is no English version package), although their entry level scissors are sold globally.
the length of the shears is 26cm
