Wrist wraps help more than tape for the long hauls, the ones with the thumb loop you can cinch down tight. But the real fix is switching to a bar with a thicker grip or adding fat grips, since a thicker bar makes you hold it more with your palm and less with your fingers. That takes a lot of the load off the forearm tendons. Also try flipping your grip every so often or resting the brick on your forearm instead of dead hanging it, sounds dumb but it saves your wrist by the end of the day.

Ouch, sounds like the shop gremlins demanded a maple tax today.

...honestly if someone's dropping 75 bucks without flipping it over to check the bottom or feeling how light it is, that's kind of on them. A real ceramic or brass lamp has weight to it, spray paint can't fake that.
