I agree with crisbac.
I have a Mai Tai insert for my P22 (which I haven't used since Covid) and it's stored with the Mai Tai insert and I don't see any indentations.
So odd, all of these didn't show up when I replied before. Thank you each for your vote of confidence for MaiTai... very helpful to have such context about the details about indentation etc.My vote is maitai insert too. Using one for my P18. Plus other bags.
I use the pockets for very small items, like travel perfume, lippies, hand sanitizer. Have to be careful on sanitizer (and of course perfume too) leakage onto your bag. The pocket helps to keep those bottle in place and not rolling around, risking the cap being accidentally flipped open.
Of course other bag inserts can do that too however maitai has one of the best quality and i feel it's worth my picotin (=
