"Teko wool and cotton socks are certified to the Oeko-Tex 100 Standard," said designer Matthew Ebbing. "This strict European standard ensures that the processing and content of a product results in no harmful or toxic substances next to your skin or left in the environment. On top of that, 100% of the electricity used in the operations and manufacturing of Teko socks is offset by the purchase of clean sustainable American Wind energy. Such an eco-friendly product as Teko had to have very ecologically minded packaging. So, TDA produced a sock package based on 100% recycled tagboard, natural soy-based ink and absolutely no glue, staples or plastic attachments to secure the product. The socks act as the package closure apparatus by passing through the back and folding over the front for display. This, in turn, also holds the socks in place. When the socks are removed the package can be opened. The socks can easily be placed back into the package after sampling for redisplay, unlike most of the competition."
