Perfect service as always

This is not a review of the product. They are just oil seals, and we expect them to be, and they are OK.
I originally ordered imperial seals, when they should have been metric. Wych bearings accepted my return, and gave me a full refund (less postage obviously). Metric replacements had already arrived by this time. Perfect service from a brilliant company. I'll continue to use Wych bearings for all my bearings and seals.
