I haven't been able to decide whether these are actual (extremely well-preserved) leather-covered buttons or a very convincing facsimile, but they're certainly vintage and ready to move onto a new project.
Even though there are only four pictured, I actually have six of them in this set, as two more were found after the pictures were finished. They are all approx. 1" in diameter, with metal shanks.
I make use of recycled packing and shipping materials, both to be eco-friendly and to minimize shipping costs. So don't worry--it might have come to you in an old television box, but your item was packed with care to arrive safely on your doorstep.
