A nice hard surface durable cover stock. My one reservation is that it is so stiff that I can only get my laser printer to take it if I bend each sheet upwards slightly and feed the sheets individually. To be fair that is probably more the fault of my otherwise great laser printer (brother 5250DN). I use this stock to make folding papercraft models and it is well suited to that function having very good resistance to abrasion and folding fatigue.
I design a lot of product that I also sell to the public. This cardstock has not let me down in terms of weight durability and not feathering the ink (from my printer).
