Thank you for viewing. These are Daiso metal rack parts. Shelf boards: 45cm x 20cm x 2 (One is not from Daiso, but from a home center, and can be used together) Poles: 47cm x 8 Shelf board fixing parts: for 2 shelf boards I used these in my study for about 3 years, but they are clean with only minor scratches. Shipping is planned via Rakuraku Mercari Bin. Thank you.
