Being a distrustful person in general, I tend to check up on reviews first whether they are reliable enough; I'm glad that they actually are very reliable, and fast too when it comes to delivery. Qualitywise these products are also outstanding. As for communication, Mr. Mark replies very fast to your questions, should one have these.
I'd recommend this store for people who look for good WW1 garments. (mine was a WW1 French overcoat, and I'm very pleased with it).
