hello,
Just came back from sitaram stationers, lajpat nagar.
I asked them for biofoam and they gave me a foam board with heavy coating on each side. The size was very small. aprox. 24x30 i asked them the price and they said it to be 350rs.
Then my driver bhaiya told me that the board did not look like the board we had taken earlier.It confirmed my suspicion that they were trying to get extra money.
I then spotted a piece that was coated with light paper and was bigger.
He said that the piece i spotted was the last one in stock. I called the casier up and asked her...
She scolded the person and took bought out a box full of the thin papered depron...
ALL THE DELHITES PL be cation while trying to buy from them..... confirm it that you have the correct thing in your hand
Positive end: I found a huge stock of balsa sheets and sticks with them
Negative:My car got towed
thanks

they will try to sell you a glossy finished one which is wayyyyyyyyyy to hevy almost 200gms per sheet.
buy the matt finished one so that you get the same thin paper that comes on dollar tree foamboard ( ft uses that)
check if both sides have paper and on the side; there are balsa sticks take one and measure the height of the depron if the height is almost the same then the size is the same...... if the stick is longer then the sheet is the 24x30 one.
you have to buy the 30x40 one... If you dont observe that, they will sell you the smaller one at the price of the bigger sheet.
RIDIKULOUS but what other option do we have???
