This card cost me over £6inc delivery (took over a week), but it is just a pre-folded card with the design printed on, as you could do at home. It looks very amateur.
The cloud design at the top of the card doesn't even fit inside the card edges!
The envelope is plain brown paper, the type a boring letter would be sent in. You can buy a pack of 50 brown envelopes from WHSmith for a couple of quid…
Totally not a presentable way of sending a card to a valentine (however good their humour may be).
I didn't expect it to be shop-quality but it's really not worth the money!
