Packing
Prepare to be impressed. We have arguably the best packing process around. We use our InstaPak machine and white open cell foam to build a custom enclosure for your piece that ensures that it's stable and secure. If it is particularly fragile or heavy, we typically opt for private courier delivery. Depending on where you are in the country, that may cost a bit extra. We also take great care to protect the tubes. When sensible, we will pack the tubes to prevent any movement. Other times, we'll individually wrap the tubes and mark their corresponding socket to preserve the bias. You can be confident that your piece will be snug as a bug in a rug.
Shipping
This piece ships to the contiguous United States for a flat rate of $125, which includes our packaging and our insurance. Of course, we'll ship anywhere in the world, just drop us a line and we'll give you an estimate – even if you're just curious.
