I'm selling items I used infrequently for about a month before switching to formula-only feeding. All accessories are included, but the silicone valve has a slight yellow tint. It doesn't affect its use. ※ A spare silicone valve is included, and it's unused. The freezer pack adapter is brand new and unused. The nipples are Pigeon's "母乳実感" (Bonyu Jikkan) size SS. All items have been sterilized. Please feel free to ask if you have any questions!
