Virgin Age Admission is a single layer onahole, there can't be "layers that separate". This sounds suspicious as fuck.

Where did you buy ? Can you take pictures of it ? Do you remind what the included lube looked like ? Can you still oppose and chargeback your payment ? What info do you have about the seller ?

I find it hard to describe what kind of hole Virgin Age: Admission is. It's certainly not a dual-layer hole but it's also not quite a single layer. I'm fairly certain NLS doesn't sell fake versions and I've had mine for almost a year from there but it started to tear apart showing its odd design after a few weeks use.

But it's never come apart so much that it somehow made it clear it's dual layer and I cut it up today after ordering the Hard version (again from NLS) to replace it and it only seems they did something weird around the inner entrance because the second half of it is definitely all one layer. But it seems that the odd method they've made the entrance can come apart and if stress is applied to the gap, it can further spread, creating a sense of dual layer splitting apart (which I've not even ever had happen in a dual layer so far). It could also be some odd manufacture fault.

Just a thought, are you sure you didn't buy the Virgin Age: Graduation instead? Afaik, Admission are single layer, whereas Graduation is a dual layer.
