Product Overview
Adjust your soil with Mag-I-Cal®! Jonathan Green Mag-I-Cal® for Lawns in Acidic Soil helps rapidly raise soil pH that's too low and stimulates healthy microbes in the soil. Healthy, lush lawns thrive in soils with slightly acidic to neutral pH levels ranging from 6.2 to 7.0. When soil pH levels drop between 4.0 to 6.0, this creates an environment for weeds to thrive and grows a lawn full of light green unsightly grass.
Mag-I-Cal® for Lawns in Acidic Soil contains pelletized calcium carbonate, or lime, in a completely soluble form that is immediately available to rapidly and efficiently raise soil pH upwards. Poor soil is often the problem in growing a great lawn and calcium is vital to many grass plant functions. Where it may take several bags of lime to balance low soil pH, Mag-I-Cal® for Lawns in Acidic has the power to do it all in just one easy application!
Additionally, Mag-I-Cal® for Lawns in Acidic contains humates to stimulate beneficial microbes in the soil.

My last batch has changed - be aware!
I have used these pads for several years now. They are generally very good and do the trick. I don't even look at other products because they are so good.
However, in this last order, they no longer have a smooth side and a bumpy side. They always had the different texture which helped in using them. I agree they are a little small which I have gotten used to, but now with both sides being smooth, they are much harder to use to wipe. Plus you don't have the advantage of the texture. This is a dowgrade for sure.

Oil and fragrance free for sensitive skin
Oil free which is good for contact lens wearers. Relatively thick textured material so I can use just one pad for both eyes. Ok for sensitive skin with no fragrance. I've used these for years and the quality has remained consistent despite the reasonable price.

A 5-star product is now barely 2-stars. Shame!
I have used these makeup remover pads for years as I wear contacts and have sensitive skin around my eyes. However, the last 3-pack I ordered (Feb 2026), the pad is noticeably sub-par. They are much thinner, there is no quilted texture on one side, and they roll up immediately when you start to rub your eyes with them. In addition, I have to use 4-5 pads to get everything off vs. previously I could easily just use one on each eye. Obviously I will go through them much faster and every time I use them, I get frustrated by how bad the quality is now. Another product victim to shrinkflation and using cheaper materials, but charging the same amount or more than before.
Do they do the job removing the makeup - yes.
Do they do so without burning my eyes or leaving an oily residue - yes.
But knowing how great they used to be, I can only give the current product 2 stars.

Excellent product!
I have used this product for years but since retired much less. However when I actually needed it again I couldn't find it anywhere and when I did buying just one was pretty expensive. So I decided to wait until the price dropped...but it never happened. I never even thought of trying Amazon but I did and got an amazing deal of a 3 pack at a very reasonable price. The oil is rich, soothing and so emollient and cleans my brows and eye lashes perfectly! I keep one in my fridge which is especially soothing during warm summer days and helps to reduce under eye puffiness. Accolades to Amazon...you never let me down!

The perfect toy for dogs!
Style: The Duo
This is perfect when you have 2 dogs who love to play Fetch! They no longer have to chase after the same ball! The balls that come with it are very sturdy, and the launcher sends both balls far enough away so that both dogs get plenty of exercise. It’s definitely worth the price!
