[Product Description]
SUO 256 ICE for dogs Cool Vest, Size L ?

■ Naturally freezes at room temperatures of 25-26°C or below.
SUO 256ICE is an item that repeatedly freezes and melts (solid-liquid) while absorbing and releasing heat, depending on the ambient temperature.
When melted and in liquid form, it freezes in the freezer in about 15-20 minutes (*)!
It cools faster than water or other refrigerants and the effect lasts longer.

[Attention! Please read and confirm]
This product uses a special material (PCM) containing food-derived oils as a cooling material.
Therefore, due to long-term storage or temperature changes, you may rarely feel a white frost-like substance or stickiness on the surface. This is due to the characteristics of the product and does not affect its safety or quality. When using, please wipe it lightly with a cloth or wash it lightly with water before use.

I purchased this last summer and used it about twice, but it didn't suit my dog... (?ω?υ) So I'm selling it!
It has been stored at home, so please understand this before purchasing. ???
