Thank you for visiting. This is a great value set that includes two types of double-edged razor heads and a handle. It includes the Yaqi Mellon with an open comb and the DSC T7 with a closed comb. I believe the Yaqi Mellon has the exact same shape and material as the RazoRock SLOC. (This is my personal conclusion after buying and comparing both.) The DSC T7 has almost the same shape as the RazoRock Mamba 70, and it's said that the shaving experience is quite similar. With this set alone, you can enjoy two different shaving experiences, and you can have an experience almost identical to that of famous manufacturers. Both razors provide a mild and gentle shave, making them perfect for those new to double-edged razors, and also ideal for those who already have other holders and want to add variety. If you purchase by 6 AM on Monday, September 8th, you will receive three types of popular replacement blades. Thank you.
