LefibonacciMaybe it's been edited since you posted, but it seems pretty clear from the description:
" This set includes six: three 0.5-millimeter black pencils, plus three 0.7-millimeter blue pencils. "
JaggiI will expect to receive the "set" of six pencils as described in "included". Calling it a "2-Pack" is ill-defined, other than the assumption of one pack of (3) .5mm & one pack of (3) .7mm pencils. It could be (2) "sets", which would be delightful, or disappointingly, only 2 pencils (a 2-Pack) of only one each. As stated, I'll expect the "included" amount.
