HARIO coffee siphon parts, FS-103. - Model: FS-103 - Material: Cotton and Stainless Steel - Type: Coffee Siphon Parts - Brand: HARIO I used to use a HARIO siphon, and I had this in stock. Although the main body broke a few years ago, I kept these parts. There are four new filters. Please refrain from purchasing if you are concerned about long-term home storage. The filter is the old type. Thank you for looking.
