I once orded from Farnell, a single microprocessor about 20mm.
It arrived in a plastic frame for 100 chips about ten inches square, sandwiched under another one. In an anti-electrostatic bag. In a standard plastic bag. Surrounded by bubble wrap. In a cardboard box. Surrounded by cardboard packing. Inside a cardboard box over two feet square.
Someone must have been having a very borjng afternoon. 😁
