One bottle, any shelf, cork kept wet. A grippy wedge holds a 750 mL bottle, or a 1.5 L magnum, tipped slightly neck-down, so the wine stays against the cork. Stack two and it lies level, or turn one around and it leans steeper.

Four soft TPU strips run the length of the curve, placed so every standard bottle rests on two of them and never on bare plastic.
The underside is soft and ribbed, so the wedge holds on wood, stone or glass. The same ribs lock two wedges together when you stack them.
Each wedge is printed in one piece in Edmonds, Washington: a rigid PLA body with the grip printed in, not glued on.
The body and the grip print in separate colors. These are the first four; more come with the first batch.
Any standard 750 mL wine bottle: Cabernet, Merlot, Pinot, Syrah, Chardonnay, most sparkling, and 1.5 L magnums too. If it came from a wine shelf, it fits.
Stacking takes two, so the pair is where most people start. The first batch prints in small runs; get on the list and we'll write when yours is ready.
We print to order, so a logo run costs little more than a plain one. Your name or mark is printed into the side wall in the grip material, flush with the body, in your colors.
A cork that dries out shrinks and lets air into the wine. With the neck a little low, the wine stays against the cork, the same reason cellars store bottles on their side.
Flip one wedge over so its curve sits on the shelf, then set the second on it, ribs to ribs. Point the thick ends opposite ways for level, the same way for steeper.
Wipe it with a damp cloth or wash it by hand. Keep it out of the dishwasher and hot cars; PLA softens with heat.
Yes. The body and the grip are separate colors, and the first colorways come with the first batch.
