What our customers are saying...

Magid consistently has the best overall cost for whatever we buy. We have had other companies quote us, but they can’t touch Magid on price or service. We had our people try it out [Magid ROC work glove] and they liked it. They said the palm coating was better and that it felt good to wear. But the best news of all was that the ROC offered 38% savings over previous glove options – that is a significant savings.
