Chose this company because I could order a small number of corks. The corks look good and the order shipped and arrived promptly. The packing slip came with some tips regarding the use of these corks that were much appreciated by this home brewer. At this point I do not know if these will go through my lever style hand corker since it will be a few months before the wine is ready to bottle. I have always used a #8 agglomerated cork but would like to try aging some wines longer than 2-3 years so I'm hoping these work. Cheers!
