Fast courier delivery by sealed package.
Plastic bottle has caps and are additionally sealed.
I bought 10 grams to get familiar with the froduct, but I can recommend, buying in larger quantities right away (40-50-100) grams, because bottles are large and shipment cost ratio.
I already tested and used hBN (+white spirit) to smooth out the surface braking disc, i felt improvement in sharper braking (better griping between braking pads) response times.
Will try to add recommended quantities of hBN to motor oil on next oil change to increase anti friction properties of the oil.

Товар отличный. Доставка в Беларусь. Зачто отдельное спасибо.
