Help Me To Buy ISOGRAPH Technical Set

H,
I need ISOGRAPH Pen for technical drawing(architecture student).
I don't know exactly .1 + .3 will do the job done or not.
If any technical student(architecture/civil) using these things please help me.
And what gms is good for A2 gateway tracing paper ?
I tried few shops(not each and every shop) at College Street,Kolkta but could not find.
At Flipkart only Rotring available and I thing its over priced.
Can u anyone tell me where to find them and the approximate price of these items ?

Try G. C. Laha Pvt Ltd of dharmatala or Bhikhan Chand Market of Old China Bazar Street.

I use those pen long ago for my drawing(illustration) purpose. Rotring isograph and Rotring variant also use staedtler pen.
Still I have couple of Rotring & staedtler pens. I bought those 20/22 years ago and they costs me aprx. rs 200 each.

Thanks for ur reply!

These are very costly.
Even at FK or ebay Rs.550+
Is there any alternative cheaper brand ?
I will check when I get time.
Usually I go via Shyambazar & Dumdum most of the day at present.

Purchasing cheap(India made) mechanical drawing pens are waste of money. Rotring is best. You can use it life long.
Try kumars concern of Shyambazar five point crossing, but I am not sure still they are dealing with art materials.

Thanks man!
U really know a lot about Kolkata.

Teacher told us to buy two pen .2 and .4.
I thinks I gonna buy one first.
Don't know will that be sufficient or not.
BTW,is Koh-I-Noor good ?
I have to check kumars concern first if not then I will try Dharmatala when I get time.

If you mean wood pencil by Koh-I-Noor, yes it is good. But you can try this for drawing.

FK always overpriced.
Rs.70 to ship a pencil.
Pencil must be priced at MRP too.

Isograph currently not available.
But,bought this pencil.
Don't know graphite or lead.

what's the price? online purchase or local store? Nice pencil.

R.150/- from College Street.
It is 0.5
0.3 or 0.7 not available.
The pencil did not come in a separate pack.
Seller gave me one pencil from a packet of 10 pencil set.

Now,can u suggest me good fountain pen & ink for illustration or drawing.
I think G-Pen and Maru Pen may not be available in Kolkata.
And I need a Water Brush Pen and Water Color Cake/Pan small box so I can carry easily.

Still I could not find Water Brush Pen.
And G-Pen or Maru Pen not available too.
May be a alternative will be a good fountain pen.

Can u tell me pls how to reach there ?
If not pls show me the google map at least.
I know little about Dharmatala area but nver went to Old China Bazar Street.
And cheapest quote I got Rs.400/- for the pen.
I will probably get next month with gateway tracing paper.

Any one can help me to find the easy way to reach there ?

Bought Rotring 0.1 Isograph @490/- from Dharmatala.
Seller said that priced has increased.
Black Ink cost Rs.60/- but blue,green,red etc color cost Rs.200/-. :shock:

I'm making mistakes while drawing on gateway tracing paper.
