First off, Ivy Hill did an excellent job of packing & shipping these tiles. All 6 boxes arrived in perfect condition & the tile is beautiful! I only ordered a sample for the 4x4 tile & the 3x8 has more of a gloss than the 4x4 and it's a slightly darker gray then the 4x4, but I'm okay with that, it's still beautiful tile. Looking forward to the finished product!
