Wooden frame, four-cut size, unused, brown, set of 4

Wooden frames, size 4-cut, color brown. Set of 4 unused frames.

Purchased over 10 years ago and kept in storage. I couldn't find the same frames when searching, so they may be discontinued.

Instead of metal clips, these frames use two flat wooden pieces that slide into slits in the frame to secure the backing (photos 2, 3, 4). These wooden pieces are attached to the backing with screws. The screw heads are rusted (photo 8).
They have glass panels, not acrylic, and come with brown hanging cords (photo 5). The boxes are slipcases and show signs of age-related damage from being moved and stored (photo 9).

There are 4 identical frames. They are not sold separately. Shipping will use recycled packaging materials.

We kindly ask for your understanding that these are items that have been stored at home for a long time before considering your purchase.
