Amazingly Easy to Build yet Very Strong!

Most people have heard of the famous "Roman Arch." You can see them in great architecture such as the Colosseum in Rome and bridges and other vital infrastructure around the world. For most people in Canada, however, they are something foreign and ancient. Ask the average person in North America: "Have you ever built a Roman Arch"? The answer for virtually all of us is no.

With this STEM Box, we aim to change that. Stop missing out. Build your own Arch!  We supply everything you need. It's remarkably easy to do with the materials supplied in this STEM Box:

(1) Correctly shaped and pre-made "voussoirs" (stones) (plus we add two extra for a total of 11)*;

(2) A simple, pre-assembled wooden frame that provides abutments on both sides to support the arch;

(3) A centring - in the form of 2 quarter-circles (the temporary structure upon which you lay the stones of the arch during construction); and

(4) An informative and proprietary S.T.E.M. Store of Canada information sheet that provides step-by-step instructions and additional background information on arches and how they work.

We make all of these STEM Boxes by hand in Canada and perform quality checks on each one to ensure that they assemble easily and accurately.  We have used very safe materials in preparing these STEM Boxes (wood, school-safe glue, etc.).

Recommended for Age 5 & Up (with adult supervision).

Notes:
(1) The stones included with this STEM Box are all identical. Any one of these stones may function as the famous “Keystone” (being the final piece placed during construction that locks all the stones into position, allowing the arch to bear weight)!

(2) The Loonie coin (not included with the STEM Box) is displayed in some of the pictures to give you a sense of the size of the Arch.

(3) We tried placing a 15-pound weight on top the arch - it held it up no problem (you can see there was no cheating involved)! Can you do the same? Maybe you can achieve even more weight?

Don’t get naked
Color: Mountains and Waters, Size: 4 Panel
In low light, you can easily see through the partition, so just know that. No assembly required. Just pop it out of the box. Good product.

I stay on your foot they don’t slip in your shoe
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
This is the only socks I wear Under Armour because they stay in place I wear a size 8, but they’re more comfortable with a large instead of a medium, but I wear both because I have them already and you can pull them to stretch them out a little bit

Great fit, truly doesn’t slide off heel
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium, Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
I’ve scoured all the lands looking for a no-show sock that was 1) thin, 2) quality, soft, breathable material, 3) didn’t dig into my feet/heels, 4) doesn’t shrink, and most importantly 5) stays on the back of my heel without a bulky non-slip rubber piece and these check all the boxes! Perfect for low profile women’s work shoes like Keds, etc. Not low enough for most flats though. I wear a women’s size 9.

So good - I’m buying MORE.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I’m gonna give you more detail than you need about why I’m buying these socks again. I’ve been the mom of girl athletes. I’ve been a model and a fashion director. I’ve worn every brand of shoe on the planet and never found a shoe that did NOT find a vulnerable spot on my foot to rub raw. Even my beloved white Jack Purcell sneakers. With that said - I don’t like socks. I’ve bought a TON of them in 35+ years.....all major brands. They shift. They lose their shape. They get holes in them and wear out too fast. Not these. I retired this year, and knowing I’d be in sneakers a lot, traveling, sightseeing ...... I bought these 6 months ago and have worn them constantly. I’ve traveled with them. I’ve washed them in hot water and bleach. The socks are like brand new. They are exactly the right cut so as not to be seen in a basic sneaker. The little silicone patch on the heel stays put. Not once have I had to dig down into my shoe and pull the sock back up. The socks have stayed soft and EXACTLY the same as the day they were new. Like I said - I am back to buy them again. Great quality!
