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 to 22cm. Since each one is handmade, there are variations in the cuts.
