Nicpro Adjustable Molds Housing for Silicone & Resin Molds, Reusable Plastic Frame with Binder Clips & Double-Sided Tape for Soap & Candle Making

This is a very simple and easy to use device to make your own resin cast mold if you are a beginner. It is definitely not perfect for it does create a good seal along the edges. The mold unfortunately does not have a tight seal bottom so the resin can actually spill out of the bottom so be aware of that when pouring. Make sure you do this outside and on top of a surface that is easy to remove resin off of. That being said, It is a very basic device. The binder clips provide a good solid seal to help maintain the side. It is customizable so you can make different sizes with the molding. It is pretty easy to peel the sides off of the resin once it has been cured. It is definitely a bit of a learning curve. I found the best results is to pour a foundation first to get a proper bottom so you can keep the resin from spilling out the bottom and ruining the mold but use your best judgment. The plastic edges are very easy to clean up and remove once the resin has cured. I have yet to have issues where it was really stuck to the resin. It may take a little force to take some off but not much. The white is easily yellowed so if you happen to leave this in the sun to cure just be aware of that. I personally do not mind that. It does make a decent mold for what I need. I was able to make a few keycaps and buttons with this. It is not perfect but again it is great for me as a beginner. The instructions are there but it is pretty easy to setup. Overall I think these are solid pieces, they make decent beginner molds, and it is easy to remove. I just wish it had a better base so it did not leak out of the bottom as much. It is a bit of trial and error when working with this.

Great product. Be sure to sticky tape the bottom completely for no.leaks

East to use, does the job as promised. Flexible design works well for various shapes and sizes.

It doesn't leak out the sides, but it will from the bottom. Use something to seal the bottom seams like putty, hot glue or caulk.

This product is amazing. Very durable and does not leak if you use the correct methods. I like making molds of miniatures for dioramas and dice and this system has yet to fail me. I highly recommend using either vinyl transfer tape, or good self laminating sheets as the base of your mold and make sure there are no bubbles to get a good seal. Then hot glue around the outside edges. But the real trick to making it leak proof is using the tape it comes with on the connecting pieces rather than the bottom. It is still very easy to clamp the pieces together even with the double sided tape on them. By using this method, I have not had a single mold leak.

I love all Nicpro products and this mold making housing is made from high quality material that's quick to assemble, comes with strong double sided tape, strong clips and detailed instructions. I've tried other brands, and regretted it immediately! The pieces fit perfect into each other also add in the double sided tape and clips and never worry about leakage again! If you're looking for a high quality product that's priced perfectly, you must try this one.

This is crap. I used as directed and all of my stuff leaked out. Too bag is waited to use it past the return time frame

The concept of these molds is good, but in practicality, unless you have something which fits precisely into it, it's going to be a waste of molding material. The box only has a limited amount of shapes and sizes you can make from it, and so far I've only found one object I could use it for. If the side walls were half the size it'd be easier to tailor to the correct size. It should be noted that this model of mold box can't be stacked to another because there's only a lip on one side, and it's pretty short in height. The double-sided tape worked fine for me (make sure you really press the box down to get it to adhere. I pressed it only a piece of acrylic sheet). There was a quality control issue in that one of the clips was missing the handles. As far as usage goes, I didn't experience any leaks, and the silicone demolded just fine without using a release agent. Overall, if this is the style of mold box you are seeking, I'd say go with one that can be stacked instead.

Amazing product with NO leakage whatsoever if you us it properly. I fixed the base to an acetate sheet and not directly to the floor or any uneven surface and I garanty you that your mold will come out flawless. Definitely recommend and will purchase some more !

Used only once and half of silicone oozed out but it’s most likely operators error. I did see it used on YouTube and worked very well.

Easy to assemble and use, very handy and versatile.
