Terumo Needles 21 Gauge 1 inch Box of 100 TW

Terumo needles are sharper and flow faster than other needles of the same gauge. The 21 gauge Terumo needles are thin wall (TW) needles- which makes them easier to insert in the skin and allows the fluid to flow faster. Although the label has changed to Thin Wall (TW), these are the exact same needles that were previously labeled as Ultra Thin Wall needles. The label has changed, the product has not.

Ordered Terumo needles. Received exactly what I ordered without any issues. Don't see anything wrong with the needles. Package arrived in the mail when they said it would. I think it was a day early actually.
Other info:
The 21 gauge needles turned out to be too large for subcutaneous hydration for this kitty. Too painful and do too much skin damage. Ended up using 25 gauge instead, which takes about six times longer to deliver the fluid but kitty barely even feels the 25 gauge needles and there's virtually no skin damage. The one thing I forgot to do was order 5/8" instead of 1" ... 5/8" is supposedly a bit faster and potentially safer. For some cats you almost have no choice but to use 21 gauge because some cats won't tolerate a lengthy fluid delivery. If the fluid is slightly warmer than their body temperature, they are *far* less likely to be bothered by the fluid delivery.

I’ve known about Terumo needles for decades - maximum flow, minimum pinch.

Terumo needles 21 Gauge...

I'm very happy with the Terumo needles (and other products) that I've purchased from Thriving Pets. Customer service is also excellent.

Thank you for carrying these!

My vet gave me 18 gauge needles for giving regular subcutaneous fluids to my cat. We struggled with getting those large needles pushed through his skin despite going for several training sessions. We are so greatful to Thriving Pets for carrying the Terumo Needles 21 Gauge that others recommended! Since that timey cat actually lays down and sits still all on his own as soon as he sees the fluids coming these needles slide right in without the forceful pushing we had to do with the 18 gauge ones the vet had given us. He is so calm throughout the process we don't even notice it might take some seconds longer.

I was utilizing these needles to provide daily 100ml subcutaneous Lactated Ringer's to my cat Maggie May, who was fighting chronic kidney disease. These were the best needles for this application. This was my 3rd order for these needles. Unfortunately, we had to unexpectedly help Maggie cross the rainbow bridge on Saturday, July 19, 2025. The needles didn't arrive until Monday, July 21, 2025, at no fault of Thriving Pets. This company has been top-notch in providing supplies for treating Maggie for her CKD. I would order from this company again and would also recommend these needles to anyone
