Black Tiger 13/15 HOSO
To understand the sizes of Shrimps:
8/12 = 8 to 12 pieces in 1kg with head and shell
13/15 = 13 to 15 pieces in 1kg with head and shell
16/20 = 16 to 20 pieces in 1kg with head and shell
So on >>>>>
The same size headless means nearly double the number.
When peeled, numbers will be more than headless shells on.
