This top is acutally the same as the bottom of the Cone Drop...When used with that bottom you will make a Bi-cone that has the hole running through the middle, left to right. A very fun, funky and interesting shape! The top is sold by itself, and is designed as an add on to the Cone Drop Quad. If you want this available for the Cone Drop Trio Large, that would be a special order, so just send me an email and we'll work out the details. Finished beads made with the Cone top and bottom measure: 10mm hole to hole, mm tip to tip 11mm hole to hole, mm tip to tip 13mm hole to hole, mm tip to tip 15mm hole to hole, mm tip to tip
