I started using towels from Pakshak some time ago. Excellent quality for a decent price. I am not sure if they are repackaged, but I have not seen the same towels elsewhere. I keep a decent stock of their 25 x 36" waffle weave drying towel, by far the best I have found. Also use the 16x24" for wax and polish work, different colors for different use. For door jambs and stuff -- whatever is cheap at target.
