Does what its supposed to at a great price and a sturdy storage case to hold everything needed.
Bubble level on first one was cracked and had to return it. But the second one we received work perfectly. We purchased a set of Staedtler pencils for the softer B2 through B6, which was a good thing because the finish we tested ended up being 3B to 2B. The pencil set we purchased had B9 through H9 and included F and HB. Purchased sandpaper sharpener (sometimes called compass lead sharpener) to flatten the ends of the sharpened pencil as required by ASTM D3363. Would recommend purchasing a "KUM A2" two hole pencil sharpener. It saves a lot of time in sharpening the pencil into a barrel also required by ASTM D3363 for B2 and harder. And the second tapered hole on the KUM A2 is tapered for B3 and softer. Everything fits nicely inside the aluminum case, including the extra items. Although we kept the pencils in the case it came for ease of locating the hardness. The liner is cheap foam, but the case is sturdy. Discarded the cut sandpaper and scotch-brite pad and used clean cotton cloth instead. To be fair, none of the other manufacturers include the accessories we purchased need to properly testing.
