This is a set of four wooden frames made of solid wood, purchased at Design Festa in 2015. I bought them intending to display Tillandsia (air plants) and staghorn ferns. However, I never got around to it, and they've been stored in the bag I bought them in, in my closet for about 10 years. I remember they cost around 10,000 yen in total 10 years ago. The items are very good quality. What you use them for is up to you. I'm decluttering, so I'm putting them up for sale.
