Rioa 10ml(1/3oz) Cobalt Blue Glass Roller Bottles with Stainless Steel Roller Ball for Essential Oil - Include 8 Extra Roller Ball (8 Pieces Cobalt Blue)

I have ordered multiple types of roller bottles on amazon from different sellers to use with my essential oils. These were one of the best I've ordered. I didn't give it 5 stars because it still was a bit tough to roll (even after leaving it upside to prime for 24 hours). I am comparing it to brand new roller bottles I buy from the oil company already pre filled with their blends that roll/glide on so easily and it just isn't quite up to that standard but still the best I've purchased to date.

This is the second time I have ordered these bottles. The first order came sealed with all bottles bottom up and with glass rollers. They worked perfectly. The second order came with the seal ripped and only one bottle down, all other were facing up, but none were broken. The rollers are metal with this order. I haven't used them yet to comment on the difference of the metal roller versus the glass roller. The label on both boxes are identical.

These are nifty little roller bottles! I use these to put my essential oil mix in and they work like a charm. The bottles are well made and the tops don't leak. The size is great and they are very easy to carry around. I put these in my purse and have never had a leak.. The bottles are really cute and the roller moves very easily and doesn't get stuck. These are great to give as gifts!!

I purchased these awesome little roller bottles recently and I liked them so much that I bought another set for my daughter and she loves them too. I put some Ion's Silk Drops in one of them, for my purse, and so far it has worked out perfectly....no leaking. I also put some lavender and a carrier oil in one to keep by my bed. I am amazed at how heavy these little bottles are, they definitely deserve a five star rating. LOVE THEM..

Really happy with these Rollerball bottles. Have used them to mix essential oils with carrier oil for easy application. The funnel is really handy and the dropper pipettes make them really easy to use. Takes a little force to get the rollerball lid pressed in (not quite sure I've done this right but it worked in the end). The lids tightly close and the bottles work well for application. Would purchase again and would recommend.

Used for a EO blend that i mixed with a carrier oil and they work perfectly. These are quite nice for the price.. I've had other rollers before that leaked and just felt cheaply made but these are much nicer. These are a simple concept but low quality can make a big difference.. even if there IS cheaper ones than these I wouldn't risk it knowing these work well.

I was excited to get these bottles - no leakage guarantee & cobalt glass was what I was looking for. However, the roller balls do not work well. It is quite difficult to get any oils to come out. Have tried 3 so far, with different carrier oils, and I have gotten the same result each time. If these had stainless steel roller balls, they would probably work better.

Bottles are nice but one of them had a scratch that may be a crack. I haven't filled it up with anything yet, so I am not sure if it's a crack. Other than that, I am quite satisfied with this item.
