At Frondescence Puzzle Co., I find wonderful artists to make beautiful plant-inspired paintings. I then craft those paintings into very well-made puzzles. This is a 520 piece puzzle. 26.5" x 20". Image reference card included with each puzzle. I designed each unique piece to be cut the shape it is. And each piece is a sturdy 2mm thickness, with a matte finish. Each box is made with 2mm thick paper (most puzzle boxes are around 1mm) and has a matte finish along with gold foil lettering. I've had these puzzles crafted to be a beautiful display, and to hold against all life throws at them. The art for this puzzle was done by Ukrainian painter Liuba P. (BarvArtShop).
