This is an entrance mat made from rush from Kyushu.
Each strand is thick, with thick skin and fine fibers, making it elastic and durable.
Igusa has the ability to purify the air, regulate humidity, and is resistant to stains.
Delicate patterns are expressed using the "bukuro triple weaving" technique, which uses plenty of rushes.
By using 100 more threads than usual(double weave), you can express fine and delicate patterns. In additional, because it uses about 1.5 times more rush than normal, it gives thickness and volume.
Urethane backing is used to prevent it from slipping.
