Arrived safely. Quite a challenge to unwrap safely. If it had been me, I would have wrapped the glass rod thinly and assembled the bottle. In the past I have used examples that had a more solid construction and a loose fitting cap. I fear this ground joint may get very stuck. For the buyer.. this was x-rayed in customs....

Buyer beware. The quality is good. The delrin valves appear to be a bit rough, but they seal. The main issue is that the scale on the burette shows 10 - 100 mL. The actual volume of the bottom half where the gas sample flows is about 137 mL. Therefore, you can NEVER read an accurate percent dissociation with these burettes using that scale. The scale needs to be percentage markers associated with the volume of the burette where the gas flows. They are useless as-is with this scale.
