Love these mini puzzles!!
I bought these for Christmas presents and they are adorable!
Loved the puzzle except for one thing: more than one piece fit perfectly in the same spots. Wish it was fully interlocking with only one piece that fits in the proper place. I also wish the tube sat on the cap to stand up with the pic of the puzzle facing right side up to look at for direction.
They are adorable in their test tubes, but the pieces are a little too small to handle. The pieces are hard to get apart if you put in the wrong spot.
Can't wait to put it together. Sent my three sisters theirs.
