These are four record storage cubes. I have owned them for many years, I believe I purchased them at the old Boston Wood location that was in Allston while I lived there.
Each cube holds between 50 to 80 records, maybe more. It all depends on what kind of collection you have. There are 64 records in the photo.
The dimension are, width: 14.25", height: 14.25", depth: 11.5"
Sold on 11/22/2023 on Facebook Market Pace for $60 (original price: $60 for all 4, $25 each)
