If you take no time has to buy every two weeks new blocks, this buy is definitely a good decision. The normal blocks of Oxford cost far more than 2, so it is worth here in any case. Nevertheless, there are cheaper and more environmentally friendly blocks commercially. I'm not saying that I am not satisfied with the quality (Quite the contrary! And it also came within two days for me to), but for people who are quite even have the time to go into town and times for blocks cheaper to buy, I would not recommend this purchase.
