The HEMSMAK series was a limited run of jars designed by @reykjavikletterpress for IKEA in 2015, to "celebrate the world of pickling and preserving". I used them to celebrate plants. Mouth blown jars are rarer and costlier in KL. They do not have joint lines unlike machine manufactured jars and are thinner, around 3mm, allowing contents to be seen with less distortion. They are the ideal terrarium vessel. I only have 3 of these jars left in my collection. I wonder how many who bought the terrariums I sold in 2015 still have them. Needless to say they're very precious.
