"I ordered festool items on 31 April.
But package do not arrive yet."
if you ordered on the 31st of April that would make it about a year, I'd be concerned!!!
if you actually ordered on the 31st of March, ask the shipper for a tracking number.....that would give you an exact delivery date.
and if you did place it on the 31st of April .......in a parallel universe that would be really tricky as there are only 30 days in April this month.
