This is a great quality set. My 8 year old was so excited when it arrived within 2 weeks (to Canada) and the tracking was very accurate. It had all the pieces needed and a few extra. The only negative is that the instructions are a little confusing and I needed to assist my son a few times. Most often the images were cut off so without seeing the whole picture my son couldn't figure it out. We worked together and finished it and he has been playing with the characters every day. He loves it!

Overall, it is a great building kit for a set that is not produced anymore.
- We received the set in about 3 weeks after order was placed. tracking worked well.
- The packaging was not good, but there was no damage.
- My 8 year old son could make it with very minor help. He had built several advanced lego sets before though.
- For us the pieces were just like lego pieces. Unless you are an enthusiast, I think you would rate them the same as legos.
- The instructions in the booklet are inferior to lego instructions but very good anyway.
- No numbered packages. Would be good to sort the pieces before starting.
- Only a couple missing parts, since we could replace them from other sets we had no problem. I've had more missing parts with original sets.

Mountain Cave - my son desperately wanted this set but I didn’t want to spend $$$ for the real set. I found this one online and gave it a try. Ordered on Dec 7th and crossed my fingers. It actually arrived the morning of the 24th. I couldn’t be any happier with the shipping time it took to come across the ocean. The original tracking link in my email didn’t work, but I emailed the company and they promptly sent me the correct link.
My son and I spent about an hour a day over the next five days putting it together. Very high quality pieces that fit tight and go together well. Instructions were easy to follow with nice color pictures. There are different configurations you can make, and the instructions show how to interchange the pieces.
I’d definitely buy another set.

I purchased this for my son’s 8th birthday, as he has been obsessed with Minecraft lego sets lately. This set came in several labeled, sealed bags, from 1-39. Unfortunately, it was missing bags 10, 11, 12, 13, and 14. My son was devastated because we could not finish building the set.

I ordered this product because my child really wants the original, which costs way way way too much. This product looks like it will be a reasonable approximation, although I haven’t yet built it. The instructions look somewhat confusing, and it did not come in a box. So it won’t work for my purposes (the non-Lego instructions are too hard for him to follow). But if you are used to unbranded versions of Lego sets, this one seems reasonable.

Do the numbers on the bags follow the order they will be used in the instructions, or they are totally random?Xi asked on August 23, 2026
The bag numbers for this set do not follow the order of the instructions. They may appear in a random order, so you will need to identify the correct bags by comparing the parts inside with the pieces shown in the instructions.For this reason, we would not recommend this set for young children or beginner builders. It is more suitable for experienced builders who are comfortable sorting and identifying parts during the building process.

I would like to purchase the Minecraft Mountain Cave as a Christmas present. Can the return window be extended since recipient won’t receive it until Christmas.Susan K Brindle asked on November 25, 2024
Yes, we will take the holiday present into consideration to extend the return window. But make sure for returning, the set has to be unopened and all the parts are sealed in the original plastic bags.

can you show more images (like of the inside of the cave)?a guy who wants a real lego set asked on November 16, 2024
The sets we offer are built with brand new high-quality third-party bricks and are compatible with LEGO, but they do not carry the LEGO logo on each brick. The model is designed to be the same as the original 21137 in terms of appearance and build, but please note it’s not an official LEGO product.
