[EX Q]: Looks nice but Very weak construction, started to breakdown by itself without falling or anything, tried to exchange it but Amazon closed the return window 2 days ago..
[EX A]: negative

[EX Q]: These are very handy! Each marker has the same color but one end is more of a thicker marker but as big as a regular marking pen. The other is a fine tip marker for doing more detailed work. Great for adult coloring books or anywhere you would need a fine point or a marker not as thick as the regular ones.
[EX A]: positive

[EX Q]: I will only use Valvoline 5w-30 in my Yaris. It's a win win when I can get it at a great price,I stock up. The price usually increases in spring and summer and drops at mid fall thru winter.
[EX A]:
positive
