Are the merchs they sell at shows worth it?

It’ll be my first time (finally!) in a Tool concert. I never thought they would come to Brazil, and I always dreamed of buying something official from them because here in South America we could only get it if we imported it or traveled abroad, which makes the price more expensive. But after looking at the website, I started to question the quality and durability of the products

Is it worth it more like a souvenier, or are they actually good? Really curious to hear what your experiences were like!
