I opened the box and noticed some white powder inside the sealed packaging of 2 of the pipettes and when I opened one of them, the paper on the back of the pipette was worn and also there is no solution in 2 of them, non are professionally sealed as there are air bubbles and looks out of alignment.

I purchased from online retailer called Manivella Ltd, limited offer Spot On Cat 6 Pipettes + free delivery - £14.90. Emailed to request a refund, no reply.
