This is something I've made on a whim. I cut apple tree wood into 2cm lengths and sand each one individually. Because it's hard, it's a good toy for pets who like something tough! ＼_(・ω・`) I don't have many apple tree pieces left, so I only have what's available. The next production will be after summer. Thank you for your understanding. m(_ _)m Length: Approximately 20cm-22cm. Each one is handmade, so there are variations in the cut.
