One-Stop Ona Shop
Wanta is hands down the best onahole supplier in the UK. Forget Lovehoney for onas, their selection is weak and their prices border on the comical (£120 for a Meiki ZXY?!? Are you out of your mind?!!). Either buy from Wanta or import directly from Japan yourself.
They boast a fairly wide selection, have reasonable prices considering all the importation has been done for you (although admittedly, they could still be slightly lower), always deliver your goodies quickly and discreetly, have great customer service and even offer a worthwhile loyalty programme.
My only real complaint is that they remove the packaging on certain products, which is annoying. That and the prices on certain onaholes are a bit steep (to the point it works out cheaper to buy from Japan and fork out for the extra shipping). Larger/heavier onas, like hips for instance, are often a real steal though. Unless of course you're willing to wait for sea mail from Japan (takes months, but is cheap).
So rejoice, my fellow crumpet munchers: Wanta has some of Japan's finest exports at hand to satisfy both you and your raging loins.
