I need to open my MBP Retina 13-inch.

I'm confused what Pentalobe screwdrivers i should buy.

iFixit tells that my MBP uses "two 2.3 mm Pentalobe screws and eight 3.0 mm Pentalobe screws" in lower case.

Some forum users tells to use P4, some others tell to use P5.

So which is correct and what size 2.3mm and 3.0mm is in P sizes?

Can i use this driver set which has "4mm Pentalobe P2, P5, P6".

iFixit seems to think it's P5. This is what they recommend in Display Assembly Replacement guide for my Mac:

P5 Pentalobe Screwdriver Retina MacBook Pro and Air (IF145-090)
https://www.ifixit.com/Tools/MacBook-Pro-and-Air-5-Point-Pentalobe-Screwdriver/IF145-090-3

iFixit seems to use their own designstions...

TS1 tip is 0.8mm, and is compatible with iPhones. iFixit calls this P2.
TS4 tip is 1.2mm, and is compatible with Retina MacBook Pros and Airs. iFixit calls this P5.
TS5 tip is 1.5mm, and is compatible with the battery screws of some MacBook Pros. iFixit calls this P6.

Like hallux said, the 2.3mm and 3mm mentioned are the lengths of the screws.
