This worked well and is quite nicely made, with the sound module housed in foam and sandwiched between two pieces of card. Would be very easy to make a personalised card with this product. I bought two and only comment would be that, in both cases, the card was a bit bent upon delivery. Not a problem for me, as I wanted to remove and use the sound modules, but not ideal given that it spoils the presentation. Would recommend the seller put something like cardboard into the packing to make sure the card doesn't get bent in the post.
