Title: Fits all Oster blenders, NOT!
Review: What a disappointment! They claimed to fit all Oster blenders but it's just not true. These aren't even close to fitting my blender, they couldn't even be streched into place. They do appear to fit another blender I have by another manufacturer so if the O-ring fails on it I have replacements. These are not as pictured, they come loose in an envelope.
