BLUE BLUE weaves its original selvedge denim in Kojima (Okayama), one of Japan's premier denim regions, on vintage power looms. The slow-running looms place less stress on the yarn, giving the fabric a uniquely full texture.
BLUE BLUE JAPAN uses both natural indigo dyeing with plants such as tadeai and synthetic indigo dyeing, each dyed by hand for a texture and depth of color that machine dyeing cannot reproduce.
STRETCH FRAISE by SEILIN & Co. uses a thick yet soft fabric with high stretch, excellent kickback, and outstanding durability, sewn with flatlock seams. It has been a signature fabric since its 1995 debut.
Nearly all SEILIN & Co. clothing is made in Japan, from BLUE BLUE JAPAN's natural indigo dyeing to BLUE BLUE's selvedge denim woven on vintage power looms. A small number of items are made overseas; each product page lists the country of origin.
BLUE BLUE uses vintage power looms because they create a fabric texture modern looms cannot. Based on late-18th-century technology, they run slowly and are far less efficient, but we keep weaving our denim on them in Kojima (Okayama).
There are no significant individual differences in our hand-dyed and handcrafted items, as we ensure all pieces meet our quality standards before shipping.
Nearly all items on SEILIN are made in Japan, with a few exceptions produced overseas. Check the specifications for country of origin details.
Store your items in a cool, well-ventilated area away from direct sunlight to prevent discoloration and fabric damage. Use breathable bags for storage.
