detached_sleeve / detached_sleeves

Should there be a distinction between just one detached sleeve (detached_sleeve), and two detached sleeves (detached_sleeves)? Or does this fall under the singular/plural rule?
The detached_sleeve tag currently only has 75 images, and its usage hasn't been completely consistent either.

I have actually used single_sleeve and detached_sleeves to portray a single detached sleeve, didn't occur to me to use detached_sleeve.

+1 for using single_sleeve detached_sleeves search instead. Separating each type of _sleeves into two tags based on plurality is silly.
