Do you have pipe tobacco?
PI-pa — both syllables are open and equally short; do not lengthen the first vowel as in English 'piper'.
Use this if you smoke a pipe. Pipe tobacco (tabacco da pipa) is less common than cigarettes but most well-stocked tabaccherie carry at least one or two types.
'Del' is the partitive article (di + il) indicating an unspecified quantity of a mass noun. 'Tabacco' is masculine. This request will often prompt the shopkeeper to ask about the cut (taglio) and flavour (aroma) of the tobacco you prefer.
