These are straws made from cedar wood veneer. They are B-grade products with partial peeling and unevenness, and are being sold at a low price. They are 150mm long, with an inner diameter of 4mm, and are sold in packs of 50. In addition to use as straws, they can be easily cut with scissors, so they can also be used as craft materials for things like Himmeli mobiles. Thank you for looking.
