what is a sleeve of nips

[Clinton]

Of course! A "sleeve of nips" is a retail term for a package containing multiple small, single-serving bottles of liquor. These small bottles are commonly known as "nips" or "shots."

Based on the information provided, a sleeve usually contains 10 of these miniature bottles. You might see them packaged together in a clear plastic wrapper or a thin cardboard box, resembling a sleeve. For example, a liquor store might sell a "Fireball Nip Sleeve," which would be a package of 10 single-serving bottles of Fireball whiskey.

So, in short, it's simply a convenient way to buy a bundle of about 10 miniature liquor bottles all at once.
