Vintage 9cm Hexagonal Baby Dolls Feeding Bottles with Rubber Teat

9cm tall, plastic, hexagonal in shape, with measurement markers on the sides.
And with a screw-on top and a detachable rubber teat that can be pointed into the bottle or upright - just like real baby bottles used to be.
Several of them have holes in the teat - for realistic feeding.
Made in hong kong on the base.

I have them in the colours shown.
The price is for 1 bottle.
