How to pack essential oils so they reach the customer safely
Small glass bottles can leak or crack in transit. A tight cap, a sealed bag and snug cushioning keep the oil inside and the parcel clean.

A small bottle of essential oil is easy to underestimate. It weighs little, so sellers drop it into a soft mailer. But it is glass, it contains a strong liquid, and a leak will spoil the bottle label, the parcel and often the other items in it. Pack for two problems at once, breakage and leakage.
Check the closure before anything else
Before packing, make sure every cap is tight and every dropper insert is seated. Wipe the bottle clean. Some sellers add a tamper-evident seal or a shrink band over the cap, which also helps the closure stay in place. After you close it, tilt the bottle and look for any seep at the neck. If you see one, fix it before wrapping.
Do not fill a bottle to the very top. A little air space gives the liquid room when temperature changes. Be sure the label you print matches what you fill.
Seal each bottle in a bag
Place each bottle in its own small sealable poly bag. Add a folded tissue or a small absorbent pad inside the bag, so that if there is a leak the liquid stays contained and does not reach anything else. Squeeze most of the air out and seal. This single step protects the label, the box and your customer's hands.
Wrap and cushion
Wrap the bagged bottle in bubble wrap or soft paper, going around twice, with extra padding at the shoulder and the base, because those are the weak points. Glass bottles hitting each other cause most breakage, so never let two touch. If a customer orders several bottles, wrap each one separately and keep them apart with card dividers or folded corrugated sheet.
Choose a box that supports the load
A small corrugated box is safer than a soft pouch. The wrapped bottle should fit with little room to move, and any gap should be filled with paper. Give it the shake test. Close the box and shake it gently. If you hear or feel movement, add more filler.
If you use inserts or moulded trays for a gift set, check that the bottles are held upright. Bottles lying on their side can leak at the cap more easily than those standing.
Label the outside
Write "Fragile, glass" and "This side up" on the box where the courier can see them. These cannot guarantee gentle treatment, but they help. Keep the invoice and any card outside the inner bag so wet or oily paper does not smear.
Think about heat
Oils can change in hot places. Do not leave packed parcels in direct sun while waiting for pickup. Store them in a cool, shaded spot and hand them over promptly.
Keep a record
Take a photo of the packed box before sealing. If a customer reports damage, this helps you understand what went wrong, and it supports the process described in cancellations, refunds and restocking. For another glass-in-transit approach, compare with packing resin art, which also stresses cushioning and corners.
Little extras that help
Add a short card with storage advice, such as keeping the bottle upright, away from heat, and tightly closed. It reduces confusion, and customers appreciate the care. Good packing keeps your oil in the bottle and your reputation intact.
