"MARTACK" was developed by "Yasaka Industrial Co., Ltd."
and then we applied for the patent
application in March 1989 and then we started to sell them.
This products have been used
as Envelope Fastener, but recently they are used for many way like shopping bags, cardboard boxes or document holders.
For more than 28 years, we have been paid full attention to improving quality of our products.
Thanks to the all customers, we could have continued to supply products that they appreciate.
In the future, we will ask customers for further quality and realize that we can listen to the precious
opinions and complaints from customers directly, and to provide customers with more appropriate price.
