[Free] W Board Green Campaign [Until the end of October]
Our company manufactures and sells construction site mats called "W Board." We are also running a campaign that offers free color processing to green for the W Board, which usually incurs an additional fee. (This applies to orders received by the end of October 2019.) The W Board is made from recycled composite materials and has been recognized for its contribution to reducing carbon dioxide emissions. This year, it received an evaluation from the Ministry of Land, Infrastructure, Transport and Tourism's NETIS (New Technology Information System) for its effectiveness and was registered as the first "VE" in domestic mat products. It is used at construction sites and events such as sports tournaments through rental companies nationwide. Additionally, we will sponsor the 28th National Transplant Sports Tournament. We will donate 1% of the sales from the green version of the W Board used for protective mats to this tournament. Through this campaign, we aim to support the National Transplant Sports Tournament and contribute to raising awareness of transplant medicine in line with October's Organ Transplant Promotion Month.
