UL 4 oz bottles?

Maybe keep an eye out in the grocery store or pharmacy. There may be something you use frequently such as mouthwash or soap or shampoo that comes in the size bottle you are looking for. I find for carrying olive oil it is nice to have a folding spout built into the cap. I would think using a water bottle (or similar) and unscrewing the cap to pour the olive oil would leave me with a sticky, oily bottle to deal with.

Really easy to do :-) (Well, if you have the tape!)

I use a 4 ounce hard side clear Lexan bottle I got at REI a long time ago to haul my oil, but when it dies I will just go to using the small 4 ounce "accessory and fuel" bottles I sell. With the tape on them they work like a charm for sunblock.

These should work for you. The flasks are flexible and can fit just about any available space in your pack.

I use a 4oz cough/cold med bottle for kids. Hasn't leaked yet!!!!

Sarah,

I presume you’re talking about these: Clear Square Containers? I’m partial to these: HDPE Screw-Top Bottles.

Also, if you order direct from Nalgene I believe you get free shipping (so don’t have to drive to REI).

Victor,

Those rumrunners are interesting. Is there anything functional about the spout being on the corner beyond ‘it’s different / cool’?

Joshua, that is the square bottle I use.
I do still carry it in a snack sized bag just in case it ever leaks ;-)

Tell me you have at least SOMETHING else in that bag… Nalgene's don't leak and carrying an extra, what, 1/10th of an ounce(?) is HERESY!!!! ;)

Yes sir ;-) Free hand moisturizing as I put the lid back on…lol!
