Chew sticks made from Beni Roman apples from Aomori Prefecture, 6-7mm thick, perfect for small animals. These are from this season's pruning (^^) After pruning, they are washed, sterilized by boiling, and naturally dried ( ^ω^ ) "Beni Roman" apples have fine-grained flesh and an excellent balance of sweetness and acidity! These chew sticks are made from the branches of rare, high-quality apples with limited production and a short harvest season (o^^o) Thank you for looking.
