floats at commend no.14 is for cliff fishing. or fish at the sea where winds ,tides, and waves are so strong.
Chinglew foats are expensive because of many reasons.
Major issue is the labour cost of the brand name of that famous float.
Material are mostly peacock tail feathers.
Don't forget the labour cost of Japan is much much higher than Thailand. The sensitiveness is totally different from 20 baht float for sure.
This is all I know but not all the information about it. sorry !!!
