But now you are partially relying on a bottle of purell that can break or leak.
The ideal manmade tiner is complete, stable, waterproof and ready to light. Everything else falls a bit short of that goal.
The cotton ball with vaseline is the closest homemade version.
Personally for the little expense I go with Tinder Quick and WetFire. All in all Tiner Quick is the most reliable and stable. The WetFire needs to stay in a wrapper or it will lose its effectiveness over time. But I love how you can put it out easily.
