Is there somewhere that we can order a sample from or did some generous soul send you a dab? I sent an email to Garry of sample shop fame and while he did say he would be adding new samples to his list very soon; he did not mention xpec or anything specific.
My complimentary sample was included in a big order of razor and products from Straight Razor Designs. To my knowledge, the vendor does not offer samples of soaps and creams, including Xpec, for purchase.
