Many different sizes you can make with one kit, flexibility for the garden is key! So bolts are extremely small and it is very hard to put together by one person but you it down after about 20 bolts. It’s tall so you will have fun filling it all up, but when your done, and it’s all setup looks really nuce and now the deep root vegetables will have all the space they need. I like them much more than wood, BPA free and feel very sturdy. Which I could afford 5 more! Flexibility with differ sizes you can make is amazing as we all know what worked on me year doesn’t always work the following year. Great purchase, get a friend to just hold the panels and it’s a breeze!
