Butterfly ‘Glayzer’ is non-sticky version of ‘Glayzer’ series introduced in the spring of 2023, and it was launched at the same time with its sticky version – ‘Glayzer 09c’. ‘Glayzer’ series is made by Butterfly’s latest tecnology applied to the top rubber family of Butterfly – ‘Dignics’ series. But, the characteristics have been adjusted to fit for ordinary players while ‘Dignics’ series aim at top players. (The relationshp between ‘Glayzer’ series and ‘Dignics’ series is same as the relationship between ‘Rozena’ and ‘Tenergy’ series.) The top sheet of ‘Glayzer’ is based on that of ‘Dignics 05’, while the top sheet of ‘Glayzer 09c’ is based on that of ‘Dignics 09c’. The ‘Spring Sponge X’ of ‘Dignics’ series is also applied for ‘Glayzer’ series, but the sponge hardness is reduced by 2 degree for more ease of use. The sponge density of ‘Glayzer’ is 38 degree under Butterfly standard (= around 50 degree under ESN standard). It is softer than the sponge of ‘Dignics 05’ (= 40 degree under Butterfly standard) and harder than that of ‘Tenergy 05’ (= 36 degree under Butterfly standard). However, according to Butterfly, players will not feel that ‘Glayzer’ is harder than ‘Tenergy 05’, because new ‘Spring Sponge X’ deforms 14% more than ‘Spring Sponge’ in case the impact speed is identical. With the announcement of the ‘Glayzer’ series, Butterfly renewed its rubber performance indices for the first time in 30 years. According to this indices, ‘Glayzer’ has lower spin performance and speed performance than ‘Tenergy 05’, but instead has better performance of drawing arc. Compared to ‘Tenergy 64’, it has better spin performance and arc drawing performance. Unlike ‘Rozena’ that makes faster ball whose trajectory is somewhat linear, ‘Glayzer’ is the rubber that is focused on the stability of drawing arc. Butterfly is explaining that, for ordinary players, ‘Glayzer’ will be much easier to use whan compared with ‘Dignics’ series.

‘Glayzer’ is based on ‘Dignics 05’. But, it is easier to use, and its price is more reasonable than that of ‘Dignics 05’.

Butterfly is appling this unified design of packaging from 2014. The accent color of ‘Glayzer’ is yellow.

The characteristics of rubber is explained in four languages on the backside of packaging.

Butterfly is explaining that ‘Glayzer’ is a high-performance rubber that combines power and stable trajectory.

In the packaging, the surface of top sheet is covered only by protection paper, while its sticky version – ‘Glayzer 09c’ is covered by both of paper and plastic cover.

Top sheet is very similar to that of ‘Dignics 05’.

The color of sponge is gray. This is ‘Spring Sponge X’ that is basically same as that for ‘Dignics 05’, but the sponge density is lower by 2 degree than that of ‘Dignics 05’.

Sponge density is 38 degree (in Butterfly standard). It is around 50 degree in ESN standard. It is harder than the 36 degree sponge of ‘Tenergy 05’. But, thanks to lower damping, player feels that ‘Glayzer’ is softer than ‘Tenergy 05’.

The constuction of top sheet is same as that for ‘Dignics 05’ or ‘Tenergy 05’. Pimples are densely arranged, and the height of pimple is normal. Two thicknesses – 2.0mm and 2.2mm – are available. Thinner sponges are not provided.

Top sheet is available in two colors – red and black. Blue, pink or green are not available.

Butterfly is explaining that the spin performance is lower than that of ‘Dignics’ series and ‘Tenergy 05’. However, it is difficult for ordinary players to feel that the spin performance of ‘Glayzer’ is lower than that of two more expensive rubbers. In simple testing at table tennis court, ‘Glayzer’ performed very well. It is very easy to use, and the spin performance is very satisfactory. Most of all, it draws really impressive arcs. For ordinary players, there will not be any need for considering more expensive ‘Dignics 05’ for best result in game. ‘Glayzer’ will be able to become another bestseller following ‘Rozena’ if it is widely accepted by ordinary players. The challenge for ‘Glayzer’ will be how to overcome the competition with many German tension rubbers those also provide good performance with similar or even lower prices.
