So after much decision I decided to get this hourglass. I had heard many horror stories about resin-based ones but as I wanted a fantasy style piece my hands were more-or-less tied. Upon receiving this through the mail, I was pleased to see it was well packaged for overseas post. I then unpacked it to find it was in good condition and the details were as I expected them to be.
There is a slight wobble as the bases aren't completely flat, but it stands straight and does not tip over, so it doesn't bother me. I then timed the sand and it is 1 minute too fast but the site does explain there may be variations so I planned for this. A 3 minute timer still suits me fine for use when running Dungeons and Dragons games, so while it's a bit of a shame it isn't more calibrated, it isn't the end of the world for me.
Good detail and sturdy build, if a little wonky.
Be careful about time accuracy, as stated these are more ornamental than time-keeping pieces.
