The Vallejo Plastic Storage Case is exceptionally well designed to hold and store Vallejo and similarly bottled paints. The case itself has a transparent top so that the colors can be identified (I put a drop of the paint on the tip of the cap), and a dense foam insert firmly holds 72 or more bottles (depending on how the owner uses the accessory storage areas). Once loaded, the case will sit flat or on the hinge edge, and ribs help keep stacked flat-sitting cases from slipping.
I have two small reservations about this useful case: 1) it is unclear to me whether the foam insert is supposed to remain stuck to the bottom of the case. The insert has two parts that do stick firmly together, but the adhesive also serves not so successfully to stick the complete insert to the bottom, and 2) one of the cases I ordered had a partially deformed insert. Hobbylinc's excellent Customer Service made getting a replacement quick and easy, but this is something to watch out for.
I'm ordering a third case, as this is exactly what I need to store my acrylics.
