This is a muffler from Black Label. I used it two or three times after purchasing it, but I stopped using it because my child didn't like the feel of it against their skin when I held them. It's still in good condition and I like it, but I'm selling it to someone who will use it. Purchased December 2025 Used 2-3 times Purchase price: Approximately 28,000 yen Total length: Approximately 165cm Width: Approximately 30cm Measurements are approximate as they were taken by a layman. Please consider this item with the understanding that it is used.
