We recently found out that the VACUETTE Safety Blood Collection Set, 21G x 7.5" Tubing, w Tube Holder from Greiner Bio-One is on backorder till June. The Germany manufacturer is having issues with production for this item, and we were informed that the needles will not be available till June. In the meantime we will be selling the same type of needle (SAFETY Blood Collection Set + Luer Adapter 21G x 34" tubing length 12" (30 cm), single-packed, sterile, not made with natural rubber latex). Link for needles The new needles will not have the tube holder attached to the end, so we will be sending The BD Vacutainer One-Use Holder Link for holders with the needles that you will have to screw on manually. We apologize about this inconvenience and are trying our best to accommodate everyones needs. 1x Box of 50 - SAFETY Blood Collection Set + Luer Adapter 21G x 34" tubing length 12" (30 cm), single-packed, sterile, not made with natural rubber latex 1x Bag of 50 - The BD Vacutainer One-Use Holder
