And then I went on amazon and got shipping boxes. So that none of my more fragile products (ie. the ones involving thin dowel rods) would go through that again.
The result is even better than expected. My next order to go out is some jump blocks in schleich scale with the accompanying dowel rod poles.
And now I have a nice protective box to keep them safe on their journey. (The best part is etsy doesn't even charge more for shipping because the boxes are still super small!)
