Customer Service is friendly and files are durable. The first time I ordered these in bulk, the 4-packs came bundled in larger boxes. The reorder did not, and it was more difficult to transport in such large quantities. Otherwise, this is a good item for a good price.
These were very hard to find at many places and your rep on the online chat did a good job of finding these for me. They're not exactly what I wanted, but very close, so overall we are quite pleased. Would have liked another color if possible, but that's the only real issue but that couldn't be helped.
