NOTE: This is an NOS item (New-Old Stock), meaning it is brand new, but very old inventory (probably about 25 years old). These came from Suntour in bulk, therefore there is no retail packaging. As always, NOS does not mean perfect - it just means old and unused. If you want new, buy new - NOT NOS.
