It's a good question! I don't know exactly... about 250-300 pcs. I will make a particular list.
Unfortunately I don't have any handmade puzzle. Unique? I have a 2x2x2 pockrt cube with plastic box. You can see on the second picture, under the yellow-green-orange "cake".
This cube has 2 blue, 2 yellow and 2 red sides.... Easy to solve...
