Custom orders will take approximately 4 weeks to complete plus shipping time from time of payment. I work on them 2 at a time, which take approximately two to 3 weeks to design, create, and pour. Items cannot be shipped until concrete has cured 21 days, longer if it is being shipped to a harsh winter location. Shipped via UPS Ground/Home Delivery to arrive in approximately 4 business days and packed in a 2-3 boxes. Full curing of concrete takes about 30 days from pouring and should not be placed outdoors in extreme hot or cold temperatures during that time. The stepping stones have been sealed with concrete sealer to enhance durability, however where winters are harsh, I recommend that they be brought indoors for preservation. Caution: Stepping stones may have sharp edges, please use caution when moving/placing stones.
