This product is specifically showcasing what bundles are on hand. If it is not listed as an option and in stock, you will have to order them from the respective texture product (i.e deepwave, straight etc.). Our bundles are 3.5 oz in weight. While 3 bundles of any lengths of 12-30 inch CAN complete most styles, it is recommended, but not required that you purchase 4 bundles for hair longer than 24 inch in the event that you want very full hair or are getting an unconventional style such as a sew-in with no leaveout.
