So, the Thread Magic Thread Conditioner Combo by Taylor Seville is pretty awesome for sewing enthusiasts. The manufacturer's product description says it helps a ton by reducing static, avoiding tangles and fraying, and even making the thread stronger.

It's suitable for any thread and fabric and can handle different temperatures—it won't start melting or anything like that.

Now, about the container sizes in the Combo set, our research shows that it's usually a small, round container, just the right size to fit in your hand comfortably. While you might not find the exact volume measurements, it's definitely designed to be easy to use and stash away as you work on different projects.

Thread Magic tends to last a good while, especially if you store it properly. The silicone-based formula is stable, so it doesn't really go bad. But, it's smart to keep it away from extreme temperatures, direct sunlight, and moisture.

There's no official expiration date, but some people have noticed changes in effectiveness if it's exposed to air. Just make sure to close the container when you’re done using it to stop it from drying out.

People have had good success using it for extended projects without any drop in performance. If it starts to feel different or isn't working as well, it might be time for a new one.

But if you take care of it, Thread Magic should serve you for a while, giving you that smooth sewing experience you're looking for.

Unfortunately, we don't have specific measurements for the container sizes, but knowing how to handle and store it will help keep it a great tool in your sewing kit.
