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.

This turned out to be one of my best purchases and so economical! I have a subscription for these brow pencils. Easy to apply, excellent staying power and so easy to carry with you. The color is saturated and perfect for my fair skin and blonde hair. You will not be disappointed! What a value!

Perfect glide and included brush
Color: Neutral Brown, Size: 0.006 Ounce (Pack of 2)
I love this eyebrow pencil because of the perfect shade of brown, smooth glide, and included eyebrow brush on the other side! I always needs to comb up eyebrows up after filling them in and it is so convenient to have the brush at the other end of the pencil. The only thing I don't like is that the pencils do not last very long. If used daily, my pencil lasts about 4-6 weeks total. However, it is affordable for that time frame so I continue to buy it for the good quality.

We Love e.l.f.!
Color: Taupe, Size: 0.006 Ounce (Pack of 1), Color: Taupe, Size: 0.006 Ounce (Pack of 1)
I love e.l.f., and at this point I feel like half my makeup bag is from them because they keep getting it right and for a great price. I got this brow pencil in the taupe shade and the color is exactly what I was hoping for. It’s soft and natural looking without pulling too warm or making my brows look too dark and heavy. It fills everything in nicely while still looking like real brows. For reference I have blonde highlights and lighter features so if I use anything too dark it looks unnatural.
The pencil tip is small enough to do little hair-like strokes, which I love for sparse areas, but it’s also easy to blend and shade quickly when I’m getting ready in a rush. The formula has a really nice texture too. It’s not too waxy or too creamy, so it glides on smoothly without smearing everywhere. The spoolie is actually useful too and helps soften everything so my brows look natural instead of overdone.
For the price, this is such a good everyday brow pencil and definitely another e.l.f. product I’ll keep purchasing.

Great for building a natural brow definition & body
Color: Taupe, Size: 0.006 Ounce (Pack of 1), Color: Taupe, Size: 0.006 Ounce (Pack of 1)
I love this eyebrow pen when I’m going for a more natural look with my everyday makeup. Great price for a great product. I brush my eyebrows out, apply with the grain of my brows and finish with another good brush throw to blend the product and it looks great. I get the color Taupe as I have dirty blonde hair, and the match is great for my brows. Quick and easy pick me up to give my brows some extra structure and definition.
