Japan Original Arnari Creation Pitchers

Vintage Japan Original Arnari Creation Water Pitchers. These are in used but good condition considering how old they are. I would guess these are from the 50's. There are 2 small chips on the mouth of the Large Pitcher. Tiny pin holes are seen but hard to see. Measurements, Large- 8"T x 4 1/2" wide @ base Medium- 7" T x 4" wide @ base Small - 5" T x 3 1/4" wide @ base Only 1 of these (small one) still have the original Japan sticker
