Mastery MST String TreeThe Mastery MST string tree design is machined (not formed) and features unique hard chrome plating so the strings glide smoothly without the use of moving parts. It has a little more break angle to prevent sympathetic overtones caused by low string tension and less surface area touching the string verses the 50s wing design. Comes with our custom stainless steel screw that's a bit longer as well as our custom made stainless steel spacer. Product

Invisible sunscreen and the brightening really helps too. Can be glossy, but if you let it absorb into the skin for 30 mins and the blot some of it off it can help with the glossy ness

Great Sunscreen
Perfect sunscreen and primer. I love how it feels on my skin. It doesn’t clog my pores. Great product.

A greasy mess
SUPER greasy. I have dry skin and it was incredibly greasy for me. It didn’t dry down at all and felt like it sat/slid around on my face. Obviously goes on clear since it’s a chemical sunscreen. Vaseline gel-like texture in your hand and applies like a silicone barrier. That part makes a little sense since I think dimethicone is high on the ingredient list. Unscented and didn’t test under makeup. I wouldn’t recommend this to anyone and I don’t think I’d try it again, which is disappointing cause I was hopeful with this one after reading reviews! The glowing reviews versus my experience makes me think folks aren’t applying enough SPF to get adequate sun protection. I’m a skincare girlie so it’s always a half teaspoon for this face.

Works well, smells great, goes on easily
Sun protection factor: 15 Sun Protection Factor (SPF), Size: 6 Count (Pack of 2)
It smells good. It goes on easily with the spray bottle. It keeps me from burning while out biking. It's a good price. Overall, a very nice product that does what it should. We carry it in our bike packs and in the car when we know we'll be out in the sun all day. Doesn't feel heavy when sprayed on so it smooths over your skin very well. Keeps me from burning.
