## Description

1.Size:5 mm x 15 mm (Diameter * length) 2.Shape:Cylinder with Pivot Ring Shape ; Quantity: 10pcs3.High-quality, Strong Magnetic, New & Clean & Cute 4.High temperature: the use of operating temperature up to 250 ℃5.Corrosion resistance: for most chemicals and solvents, showing inert, strong acid and alkali resistance, water and a variety of organic solvents 6.High lubrication: the lowest coefficient of friction in solid materials7. Low temperature resistance: good mechanical toughness, even if the temperature dropped to -196 ℃, can also maintain a 5% elongation 8.No adhesion: with the smallest surface tension in the solid material, no adhesion to any substance9.Weather resistance: long-term exposure to the atmosphere, the surface and performance remain unchanged 10.Non-toxic: with physiological inertia, as artificial blood vessels and organs long-term implanted in vivo no adverse reactions

Review: Works as expected. - Yep…good to have several of these. Some get lost and some get accidentally dropped into the fermentation chamber with the wort. The middle raised area, used for reducing surface contact to give better reliable stir, works great. 16hrs on the stir plate, yeast starter was ready to go. Fermentation was noticeably apparent within 4hrs of pitching the yeast. Highly recommend for your starter yeast.
Review: Works well - Works well with my magnetic stirrer. Great for agitating shimmer ink in slim bottles like Ferris Wheel Press
