This item only includes 1pc of the cog. Since there are 10pcs of the cogs and one SPEC tag packaged in a single Shimano retail bag, please understand that it is impossible to ship each cog within the retail bag unless you order 10pcs of the cogs at the same time. Therefore, we'll ship the cog without the tag shown in the picture.
