This is firgi's silicone divider. I bought it late, and ended up switching to complete separation after only using it once. Since it was only used once, I believe it's in very clean condition, but please refrain from purchasing if you are concerned as it is a used item. Purchase price: 3,980 yen Purchased in July 2025 from KIDSMILE on Rakuten. The box is not included, so it will be wrapped in cushioning material and shipped in a paper bag or similar. *Immediate purchase welcome. Please refrain from price negotiations.
