Excellent Product! HDPE Dividers

I purchased (2) 36" long 3/4" thick HDPE Dividers, as replacements for the thinner 1/2" dividers for my Epoxy Resin Mold from a different supplier (MRM). I cut these to 24" and used the excess to make clamping blocks. These thick dividers are very sturdy; and an upgrade from the thinner 1/2" originals which had started to warp. I had previously been using 2x4s covered in tuck tape to replace the warped dividers. This allowed me to maximize the space in my resin mold and get a full 6 boards in my pours, versus the 4 with the 2x4s covered with tuck tape.

No Seal Forms

I love these forms. They make the whole process of creating charcuterie boards and serving trays way smoother.

Works great!

Mold worked awesome! Project came out beautifully. Had one little issue in a corner where my wood must have slid under the corner seal a little bit and stuck there. Will figure out a repair for it. Otherwise it was awesome and looking forward to buying a couple more sizes soon!! Thank you

It was great to get my package. I ordered two different lights to use with the current more that I have to make a smaller mold within the larger mold. I noticed that on one end, it was cut at a slight angle, which look to me to match the sides of my mold. I just have to clamp them in place, caulk the edges.

The only issue I have is the rectangle frame is bowed. Going to try and put hot water in it to help it level out.
