Seriously, you need to relax about this, like we discussed 2 weeks ago.
Modern silicone materials do not shrink anywhere near as quickly or severely as older silicone types. These days, it's no concern unless it's been many, many weeks.
I promise you, I'm saying this in a completely friendly way:
Please stop obsessing about the process and the waiting time. This is completely normal for CIEMs. It is very common for the process to take 4-12 weeks, depending on how much workload the CIEM company has at the time you order. In your case, you ordered at Christmas, and just after a major product launch, and just after a Black Friday sales rush.
Add all those factors together, and you really should not expect to receive your CIEMs until the end of January - maybe even mid-to-late February.
It's not something to worry about
It's something to just accept, relax, and be patient about.
Almost every person in this thread has experienced having to wait 2-3 months for one of their pairs of CIEMs, from one vendor or another. As I mentioned to you before, my CIEMs from Unique Melody ended up taking about 13 weeks. I think I recall my Spiral Ear SE-5s taking around 2 months.
