Delivery at this size
Whether a pack ships free depends on the order value against our delivery threshold, and this tier's position relative to it is stated below rather than implied.
A single 10 × 10ml vial order qualifies for free UK delivery, because it is at or above the £30 threshold.
Storing ten vials
The storage condition printed on the label applies to every vial in the pack, sealed or otherwise. Vials are unaffected by pack size — ten sealed vials keep exactly as one does.
