I like this felt tipped liquid liner pen, from the Sephora Collection. It is easier to use, than a regular brush tipped liquid.
yes, the felt tips are the best. hourglass's felt tip liner is long lasting as is the ilamasqua one. they are amazing. I haven't tried the sephora one to know if it is smudgeproog and long lasting.
I like LORAC's Front of the Line. It comes in a pen form, easy to apply and line with precision. The tip is flexible allowing you to make either fine or thick lines. Its also waterproof and smudge proof. I really like this liner - I'm definitely not an expert and I'm always in a hurry and this product allows me to achieve pretty decent eye looks. It also doesnt irritate my contacts. Hope this helps.
