Sorry about the postage to UK as length means  that it does not qualify for Royal Mail small parcel so its a courier job (no wonder they lose money)!

Will post worldwide-paypal only.

I always combine postage if buying more than one item.Trusted experienced ebayer seller with 100% lifetime feedback record & no quibble return policy.

Please see my other items for sale:all my listings can be picked up,cash on collection & bidders most welcome to view before they buy.
