Bottleneck is a tricky packing puzzle that Tom Lensch crafted after what must have been a moment of shock at this lovely puzzle design. I can't say more without spoiling things, but let's just say that it loves to prey on your assumptions!
I'm not sure what woods the puzzle is made from, but while it's hard to see for sure in the pictures, I can confirm that all of the pieces are a different type of wood from each other.
I accept and prefer using Zelle as my payment method of choice.
I
accept Paypal. I prefer Friends & Family due to the IRS tax rules.
But if you rather pay with Goods & Services, I will accommodate that
preference.
I accept Wise for international buyers.
I am willing to consider other payment methods.
Shipping is USPS or UPS
Buyer chooses the shipping service and shipping speed, First Class or
Priority (assuming the package is under the weight limit for First
Class).
Insurance is optional, but buyer has to cover it if it is desired.
I ask the winner to hold off on paying until after I calculate and
message final shipping costs to be added to the final bid.
