I was the one who sent you the pm about mousepinsonline. I actually have never posted publically before, but I am a lurker from way back. I wouldn't be posting publically now except for the comment about the pins from mousepins being Sedesma pins. I don't know what would have led the other poster to draw that conclusion, and I didn't think it was fair to the site to let that comment stand uncorrected.
I can tell you that the pins we received were definitely not Sedesma pins. I know Sedesma pins because we received some through Ebay and were not happy with them.
From our communications with the owners of the mousepins site, none of their pins are Sedesma pins (we checked before ordering). They are all ProPins which are from a different company altogether.
We ordered the grab bag, and received a really nice assortment of high quality pins. They even threw a couple of extra pieces of ProPin merchandise in with our order. All of the pins we got say ProPin on the back along with the Disney stamp. If you look at PinPics.com, you will see that ProPin is a German company whereas Sedesma pins are made in Spain.
My dh and I are WDW fanatics --- so much so that we just had to join the DVC in 1999, and have been annual passholders since then. Our dds began pin trading a couple of years ago, and we are always looking for less expensive ways to support their habit. My husband had gotten fed up with Ebay when we received the Sedesma pins. We came across mousepinsonline and decided to give it a try. We were really pleased. I assure you the site is legitimate. I can also assure you that none of the pins we received were Sedesma pins.
Not to "gild the lily", but the pins we received were as nice as any we have bought for three or four times the price at WDW. We were impressed enough that we just ordered more pins from the site for our upcoming May trip!!!!
Hope this clears up any questions you might have.
