These are hardwood log slices. Currently, the 100-piece series is popular, so there is a limited stock. Therefore, we cannot accept orders for the 100-piece series specifying the size (e.g., "more of X cm"). The reason we are selling them at a significantly reduced price is because the sizes and types vary. We appreciate your understanding. This is a set of 100 pieces with random diameters of 3-8cm (thickness 1.0-2.0cm). The wood types are not just one type; they are mixed randomly, and that's why we can offer them at a lower price. (The log slices in the image will be mixed and delivered randomly.) They are basically circular, but there are a few oval ones included. Use them for making holes or for Christmas decorations. The cut surfaces are unpolished, but they are smooth and not fuzzy. Also, they have not been treated with paint or other finishes. The bark is also left in its natural state, with some slight lifting. They have been dried to some extent, so you can use them immediately. However, please be aware that cracks or splits may occur depending on the environment. Please purchase with the understanding that these are natural products. Instant purchase without comments is welcome.
