Camping paper toilet seat covers

Hello all,
Does anyone know where to buy paper toilet seat covers the camping type. Usually you can buy them in chemists, but here in Spain you get blank expressions. Cruz caravanas has never heard of them. Thanks.

Thanks Marcliff, I've been buying from Amazon U.S, too much time and money for a bit of bum comfort, I'll try your Recommendation Amazon.es
If I can get the article wording correct.

I think I saw them in the Chinese or consum but I have seen them around London Marabu

Hi,
I bought them from EBay a month or so ago. I imagine, they will post them to you. Hope you get sorted but if not, I am coming to a Torrevieja at the end of a July and could bring whatever you needed..if this helps,let me know.

Hello Mac3blade,
Thanks very much for your kind offer, I'll try ebay first and get back to you
If I have any problems.
Regards,

Thanks Dot, I'll have a search.
