Your box of pipes should get there……eventually. I sent a box of estates to Dublin last year, it spent over three months (!) sat in Irish customs, before being delivered.I'm waiting for a Peterson that has gone radio silent with An Post as well but not nearly for as long. I'm however also waiting for a parcel to return to me that I sent to smokingpipes.eu with 14 pipes that I might sell to them that never got delivered. Both me and SPE had contact with An Post several times but they messed up at every turn. That experience is making me more worried about the Peterson pipe I'm waiting for since they clearly have problems.
Anyway, enough of my whining, congrats on your new pipe!
Too late for you now but if you buy again use the UPS shipping option at checkout. AN Post are an absolute joke at best.
