These are an amazing value.
1. Very Strong
2. You cannot make these at home for even 3 times the cost.
3. Just a great box.
If you take the cost of a quality, sanded sheet of 5/8" plywood, add in the tools required to cut it, then route the edges, then drill the holes, you would be at over 300 dollars US in materials and tools. Do you have the time and skill to make these?
I have 2 of these now. They are absolutely strong enough to support my weight and double that. I have no qualms using these as plyo boxes, impromptu seating, as a drum, and just as a useful box.
I will be buying more. Hoping the larger size comes back in stock. I will need a few of those as well.
