If I purchase the K10s Ill post an update. However I do think this is perfect for travel and touch-ups. I spent a lot of time pricing out supplies for a group watercolor activity and the prices of these brushes cant be beat. Recommend 100%. I put a large cargo carrier on top and it felt secure on a 7+ hour drive. I dont know whether to give this another chance because it is so good. Quindi per meno di 100? abbiamo ottimo suono, colori, metodo di ritrovamento, un cavo anti perdita (vedi EarPods), LE CONSIGLIO A TUTTI I luv the bang drinks. I haven?t tested dropping it for obvious reasons, but if the event ever occurred I do feel certain that my AirPods and the case would be extremely safe. I drained my iphone xr, then i plugged it when it was at one percent.
