Lynnz, they look very similar to mine that I bought many years ago from the Upland company, but I think it's more than five years that they've been out of business. I think you would be very happy with the molds from Nurture Soaps, here
https://nurturesoap.com/19-soap-molds I've bought their molds and I think they compare very well to the ones from Upland, which were the first I ever bought, and love dearly. By the way, from your picture, I see you had the same thing happen as I did. After using the mold for a while, I was upset when trying to put it back into the wooden box, and noticed that the sides were bowed, and even when filled with soap batter, there were those "ripples". But oddly, when I took it out of the box, it was straight! So I finally figured out that the mold wasn't bowed at all, it had simply stretched, lengthwise, with use. So I removed one of the wooden ends of the box, and replaced it with a much thinner piece of wood, so now the mold had room to straighten itself out, and no more ripples. So if you buy a mold, intending to build your own box, you may want to make the box slightly longer than the mold, or have some way to adjust the end, to prevent this from happening again.
