What are the exact dimensions of the 20ml and the 30ml vial: diameter and height?

I do no know, I purchased the 10ml vials. It says 50 x 22 mm on the box.

Does the rubber seal on the inside of the vial have a small gap in the rubber to allow all of the med to be drawn up, or is it continuous on inside?

I've never seen what you mention. The rubber is a one piece seal with no holes. When you insert a syringe into it, it makes a hole, however, it seals up (this is the self healing feature they're talking about). So you tear the plastic cap off permanently, which exposes the rubber seal. It seals up so tight, that the contents can not escape even when upside down.

For the seller: What is meant by "self-healing"? I've never seen that before, aren't all multi-dose vials just made from identical butyl rubber?

Yeah it’s just like every other vial. Normal rubber tops

Perfect for Safe and Easy Wegovy Injections

I'm a big fan of Ks-Tek Sterile Empty Vials for my Wegovy injections. Here's why:Safe and Secure: These vials are pre-sterilized, which gives me peace of mind knowing I'm not introducing any contaminants into my medication. The self-healing injection port is a great feature too. No more worrying about damaging the vial with repeated injections.Easy to Use: The flip-off aluminum cap is easy to remove and replace, and the self-healing injection port seals securely after each use. This makes the injection process smooth and efficient.Multiple Size Options: Ks-Tek vials come in a variety of sizes, so I can find the perfect one for the amount of Wegovy I need for each injection.Overall, I highly recommend Ks-Tek Sterile Empty Vials for anyone who injects Wegovy or other medications. They're a safe, convenient, and cost-effective option.
