The plastic bottle neck rest allows you to easily carry and transport plastic bottles. It consists of a plastic ring or holder that fits around the neck of the bottle and has a handle or strap attached for easy portability.

Whether you're walking, hiking, or traveling, the handle or strap makes it easy to carry the bottle, and with the neck collar and handle, you can carry the bottle hands-free, which is handy when you need to use your hands for other things. The stand gives you a firm grip on the bottle, helping to keep the contents from dropping or spilling.

Usually, they are sold in packages or in bulk, and the unit price decreases as the quantity purchased increases.

Generally, plastic bottle neck supports range from a few cents to a few dollars per piece. However, it is important to note that prices can vary widely depending on the exact type and quality of the bracket.

It's also worth noting that some plastic bottleneck rests may be sold as part of sets or kits that include other accessories such as carabiners or straps, which can affect the overall price.

To accurately estimate the unit price of plastic bottle neck rests, it is best to research different plastic bottle neck rest manufacturers and compare their prices and products.
