Banggood

Great product. Very happy with my purchase.

bought for drawing aerofoils, to replace a set from last century that went missing - nice solid plastic with undercut on both surfaces, so the edge won't bleed ink if you use a rotring or other "wet" pen definitely value for the price

Packed well and item arrived safe and undamaged. Great quality material. Seller sent it fast. Thanks a lot!

edges are smooth, perfect value for the money.

Good quality recommended product..

Cheap but not the best quality curve transitions aren't very smooth and have rough edges.

very good.

Perfect

took forever to get here but look the part

in good quality plastic, very smooth that will help the pen or pencil to move along when drawing. No need to mention about shape because every brand has the same. I am happy to order these from banggood except one thing : I ordered 4 items but just received 2, the other 2 are still being processed and I don’t know when they would be delivered. I am longing for them so much and check the order many times a day.
