We introduce the concept of $p^n$Bext projective abelian $p$-groups and show that they form a class which properly contains the class of all $n$-balanced projective $p$-groups. This somewhat enlarges a result due to Keef–Danchev in Houston J. Math. (2012).
Keywords: balanced projectives, $n$-balanced projectives, $p^n$Bext projectives.
