The moulds in all our Mosaic Stepping Stone Kits are reusable. If you plan to make more mosaic stepping stones, you can use a refill pack. Our refill packs contain a set of frost resistant ceramic tile pieces, a new design template, card disc and sticky transfer paper. This makes it much more economical to make a full set of stepping stones for your garden. The cement mixes are not included in the refill packs. If you are making a set of mosaic stepping stones. it is much more economical to buy this yourself locally and it keeps the weight (and therefore the price) down.
