Refill Pouch Hanging Nozzle MUJI (Muji) Set of 2 (1 opened) I bought these without knowing they were for MUJI products only. I opened one and tried to attach it to a commercially available shampoo refill, but it didn't fit. That's when I realized they were specifically for MUJI products. I haven't used them, but I did open one, so I've listed them as "Like New." For those who use MUJI products, please consider these. I will ship via Yu-Packet Post Mini. Please refrain from price negotiations. Returns are not accepted.
