Can you help me?

Dear Readers, I have been in the market some time for an art supply..and I wanted to search out some opinions.. Please leave a comment if you have any info to contribute..I would really appreciate it!

I'm looking for an oil pastel product..in a pencil. Something like an eyeliner that you maybe turn on the bottom to get more product to come out the top.. Maybe something that you can sharpen in a manual pencil sharpener. NOT a crayon or a stick. I want to be able to make detailed marks on my acrylic paintings. Chalk pastels will not do.. crayons no good..and an artist pencil is not "smooshy" enough. I was looking at products like these (link), have you tried them before? I'd love to know your thoughts!

Work in progress..
