Non Identical Twins

One of these things is not like the other.

The orange one is a ‘pop off’ cast and the blue is a standard fixed body cast.

After a few comments from people unaware of this change I’ve added some info from an earlier WiMT post of mine. I didn’t realise this wasn’t widely known yet.

Edited cut and paste from the first paragraph of the WiMT post linked in the comments.

“It wasn’t until I got home that I noticed it was different to the blue version I got a few weeks back. This new one had a metal base! On closer inspection I could see a small lever to disengage the body from the base which the blue one dosen’t have.”
