>>457 Can I buy a product that is the same type of ASIN above at Amazon Canada? How long had you been selling a type of products has a nylon strap with a marker for adjustment in Japan? Did you change a kind of wood or quality of the wooden ring?
>>458 I bought the same product in Japan. I sent this mail because I have some ideas of improvement for making your products better. I hope this will help developments.
First, the buckle is hard and difficult to adjust the length, so it would be better if it can be adjusted easily. I think it's useful if there are marks on the strap every centi meters to adjust both straps to the same lengths. I don't care the price will be up, so i hope you use fine wooden material like a birch to make a wooden ring. The 4 or 5 meter long length of strap is too long for home use so I want it to be 3 meters.
